Transcript: Gregor Mendall's research Click here By the Rainbow Group Dive into his research? Gregor Johann Mendel, or the father of genetics, was the man who discovered the subject of genetics. He was born July 22 1822, and died January 6 1884. He was also a meteorologist, a teacher, and a botanist Our Experiment Look at our activity Data Table Total number of students: 16 Trait 1 Number Trait 2 Number Free ear lobes: 11 attached ear lobes: 6 Hair on fingers: 5 no hair on fingers: 11 Widows peak: 4 No widow's peak: 12 Curly Hair: 6 Straight hair: 10 Cleft chin: 4 Smooth Chin: 12 Smile Dimples: 4 No Smile Dimples: 12 In our project, we took a class survey to see the dominant and recessive alleles and traits. Although we predicted that the dominant traits would be the most common, we were proved wrong. The most common traits in our class were mostly recessive. But, if we were to do our test with a larger group of people, and in a different place, the results might differ. our hypothesis Pea plants Look at his research Mendel started his experiments with purebred plants-an organism that is the offspring that has the same traits as previous generations the offspring looked similar to the parents, and that some features were more apparent than others. These are called traits. Alleles keep going!! Alleles are the different forms of a gene. An organism's traits are controlled by the alleles it inherits from its parents Some are dominant, when the trait always shows, and some are recessive, which hide when the dominant allele is present The F1 Generation This test was started by crossbreeding a short plant, and a tall plant. The result of the offspring was a tall plant because the tall trait was dominant. F1 Generation The punnett square The Punnett Square The punnett square determines what traits will be dominate. The uppercase "A" is the dominate allele The lowercase "a" is the recessive allele. If the dominate allele is present at all, the recessive trait will not show up. Click the home button
