GENE 320 Chapter Notes - Chapter 3: Null Hypothesis, Consanguinity, Dihybrid Cross
Document Summary
Mendel"s discoveries towards genetics was profound since he had gured out dominant and recessive genes/traits without any knowledge of what genes actually did to organisms. It was also extraordinary that he was able to pick peas as his model organism, since the genome of peas is quite simple compared to other species. Showed the generation to generation change of offspring. Helped identify dominant and recessive traits and showed which offspring could be assumed to be heterozygous or homozygous. Reciprocal crosses were done with the plants to show that the monohybrid crosses were not sex-dependent. Unit factors in pairs - genetics characters are controlled by unit factors existing in pairs in individual organisms. Dominance/recessiveness - when two unlike unit factors responsible for a single character are present in a single individual, one factor is dominant to the other, which is said to be recessive.
