ANTA01H3 Lecture Notes - Lecture 3: Genetic Drift, Gamete, Telomerase Reverse Transcriptase
Document Summary
Traits in offspring are not passed solely by either parent traits are passed in small, independent packages from both parents: we call these packages genes found what evolution was working on. Mendel, wallace and darwin all publishing at the same time, but there may have been a language barrier or else they could have come up with more theories. Cross bred green peas with green peas. Offspring of any generation always had green peas. Cross bred yellow peas with green peas. All offspring plants (f1 generation) bore green peas. Cross bred green offspring plants (f2 generation) had green peas and some had yellow peas. Ration of green to yellow plants in f2 generation was always 3:1. What would the punnet square look life if we crossed: Green and green: heterozygous state: individual receives two different gene forms from parents. Dominant genes: always expressed in the individual who carries them such as green peas.
