Monohybrid Cross

In the last class, we learned about a monohybrid cross. For the most part, I understood how to do it. I got a 5/5 on my quiz, so that should show that I know something. I think that I have cleared up any uncertainties by now.

An example of a monohybrid cross that I will make up right now involves the breeding between a homozygous right handed father (RR) and a heterozygous right handed mother (Rr), with the dominant trait being right handed (R) and the recessive trait being left handed (r).



As shown above, this match results in a genotype ratio of 2 RR: 2 Rr and a phenotype ratio of 4 right handed : 0 left handed.
