  2. Gregor Mendel was a biologist who worked with pea plants to show inherited genes. He showed how genes are passed down from generation to generation. He was not a scientist but a monk who taught natural science in high school. He did ground-breaking work with the theories of hereditary that were around in the early- to mid-1800’s. He came up with the three laws of hereditary genes. The first was sex cells of a plant may contain two different traits, but not both of those traits. The second was characteristics are inherited independently from another, which is the basis for recessive and dominant gene composition. The third was that each characteristic that is inherited is determined by two hereditary factors, or genes, with one from each parent.

  3. Gregor Mendel lived from 1822 to 1884. Mendel was also interested in meteorology and the study of evolution. He was inspired by his professors and peers at the monastery where he went to school. During a seven year time span Mendel tested around 29,000 pea plants.

    His studies were mainly focused on the characteristics of plants. He was the first person to analyze the characteristics of successful generations of living things. Mendel crossbred and purebred pea plants noting the characteristics of each new generation. Gregor noticed that there were some traits that were dominant and others recessive and these came in a numerical pattern or ratio (which was around 3:1). Mendel’s experiments brought forth the laws of Segregation and of Independent Assortment.

  4. Gregor Mendel was the first person to trace characteristics of generations of a living thing. His work wasn’t recognized for 34 years. The reason why he started researching in the first place was because of his interest in nature. He was interested in meteorology and theories of evolution as well as plants. He studied seven basic characteristics of pea pod plants. By paying attention to these characteristics, it led to the discovery of three basic laws.
    His work and basic theories led to be the basis for the study of modern genetics. His studies led to the discovery of particulate inheritance, dominant and recessive traits, genotype and phenotype, and the concept of heterozygous and homozygous. He found actual proof of existing genes.

  6. Gregor Mendel was a Central European Monk that researched genetics for years and years and was a high school mathematical teacher, and a physics teacher. While Mendel’s research was with plants (the basic unit of heredity), it tied together with plants and animals because heredity is essentially the same for all living forms.

    Gregor Mendel is most known for his study of the pea plant. While studying this he noticed that certain traits show up in offspring without any blending of parent characteristics. One of his most known experiments is cross pollination, it deals with what is dominant and what is recessive. Such as: yellow is dominant over green and round is dominant over wrinkled. Mendel’s certain basic laws are: Heredity factors do not combine, but are passed intact; each member of the parental generation transmits only half of its hereditary factors to each offspring (with certain factors "dominant" over others); and different offspring of the same parents receive different sets of hereditary factors. Mendel's work became the foundation for modern genetics.

  7. Gregor Mendel was considered the father of genetics for his study and work on genetic properties. Gregor began as a monk in Austria. He first began experiments on pea plants in his monastery. He tested if by cross breeding different plants with different types of flowers and characteristics. He found that even though plants don’t show the parents characteristics the characteristics stay hidden in the child. This made the Laws of Heredity and started genetic study. Mendel became the Abbot near the end of his life and had to stop his studies.

  8. Gregor Mendel was born on July 22, 1822 in Heizendorf, Austria. He studied at St. Thomas Monastery in 1843. He was the son of a peasant farmer and he was ordained into priesthood in 1847. He then became a teacher and was assigned to a secondary school in the city of Znaim. There he failed the teacher certification. In 1851 he started training to be a teacher at the University of Vienna in the subjects of mathematics and biology. In 1856 he became ill and he quit teaching. He then returned and was promoted in the monastery to Abbot. He died on January 6, 1884.
    He is most famous for coming up with theories of heredity. Using a pea pod he discovered three basic laws which governed the passage of a trait from one member of a species to another member of the same species. The first law states that the sex cells of a plant may contain two different traits, but not both of those traits. The second law stated that characteristics are inherited independently from another (the basis for recessive and dominant gene composition). The third theory states that each inherited characteristic is determined by two hereditary factors (known more recently as genes), one from each parents, which decides whether a gene is dominant or recessive. In other words, if a seed gene is recessive, it will not show up within the plant, however, the dominant trait will. Mendel's work and theories, later became the basis for the study of modern genetics, and are still recognized and used today.

  9. Gregor Mendel was an Austrian Monk that worked as a biologist and discoveries with hereditary became the basis of the modern theory of genetics. He was first inspired to experiment with hereditary while studying in Vienna, a biologist there named Frank Unger that had a view on inheritance unaffected by any spiritual beliefs. Mendel then decided to do experiments at the monastery, this was against the bishop’s rules, but he decided to ask the abbot. He decided to conduct the experiment with the garden pea, Pisum, which he grew in the monastery garden. When he published his first book about his experiments, no one understood it, not even people that worked in the same field. His work was unrecognized for 34 years. He spent the rest of his life committed to his duties at the monastery. His work was finally recognized in 1900 by three independent investigators. But it was not fully recognized for its full significance until the 1920’s and early ‘30’s.

  10. Gregor Mendel was a huge influence on the findings related to genetics. During his time he was not well known or credited for his work. He was a high school mathematical teacher, but spent time studying genetics through pea pods, which is what he is most known for. Mendel discovered hereditary traits that were passed down through generations.

    During his pea pod experiment he discovered that there were both female and male reproductive organs. And how traits from both were passed down to their offspring. He also discovered that some characteristics were dominant over others. Gegor’s discoveries lead us to where we are today.

  11. Al right well gregor mendel was born in 1822 and died in 1844 and when he was a young man he spent most of his time and money teaching biology and then he bread thousands of pea plants which he developed the mendels law of heredity. He also looked for how the pea plants color appeared and shaped was developed. Amen

  12. Gregor Mendal was the sun of a peasant farmer but he always wanted to teach. In 1947, he tried to get a teaching degree form the city of Znaim, and didn’t get it. In 1951 he went to the University of Vienna to train to be a teacher of Mathematics and Biology. In 1956 he again tried to get a teaching degree but he withdrew because he quite because he got really sick. He never tried to get a teaching degree ever again, but he continued studying Biology and Math.

    Mendal was known for his “theories of heredity”. He used simple pea pod plants and studied seven basic characteristics. By tracing these characteristics he discovered three basic laws which found the path of a trait from one member of a species to another member of the same species. The first law says that the sex cells of a plant may contain two different traits, but not both of those traits. The second law stated that characteristics are inherited independently from another. The third theory states that each inherited characteristic is determined by two hereditary genes. Mendel's work and theories, later became the basis for the study of modern genetics, and are still recognized and used today.

  13. Gregor Mendel was the only son of a poor farmer. Eventually he began studying at a monastery and then became a priest. He then realized he should be a teacher. This made him able to begin experimenting.
    Gregor Mendel developed the basic theory of genetics and the law of segregation through experiments with pea plants and cross pollination. This is an important discovery for us because it helps us understand how inheritance and genetics work. This could be useful for trying to predict future results.

  14. Gregor Johann Mendel was born on July 22, 1822 in Heizendorf, Austria as a child; he wanted to be a teacher. When he took the qualifying exam to be a teacher, he failed. In 1851 he began going to school at the University of Vienna to study to become a teacher in mathematics and biology... He is commonly known for his study of genes and traits with pea plants. He crossbred thousands of pea plants to learn about inherited traits passed on from generation to generation. His studies led to Mendel’s Laws of Heredity. His studies led to the discovery of particulate inheritance, dominant and recessive traits, genotype and phenotype, and the concept of heterozygous and homozygous.
