Question
w a uid you expect to see on the gel? 7) You are performin g crosses in your experimental animal and find the following: Cross Phenotypic ratio of progeny 1) yellow female x brown male | 2 brown: 1 yellow 2) yellow female x brown male 2 brown: I yellow: 1 rust 1 brown: 1 yellow A. How many genes are involved? B. What are the dominance patterns for the alleles? C. Suppose when the yellow progeny from cross 1 was mated to the yellow progeny of cross 2, the phenotypic ratio of the progeny was 2 yellow:1 rust. What were the genotypes of the parents?Explanation / Answer
7a) In the first cross, it suggests that brown is dominating over yellow. Now the second cross is suggesting that here a third gene is also present, which expresses under some condition. That condition may belong to the recessive epistasis where plant may die. Therefore, here 3 genes are involving.
7b)
Now we get the dominance order as Brown> Yellow> Rust.
