A researcher crossed a green- spotted salamander with a red- spotted salamander. All the progeny were red- spotted. A male and a female from this group were crossed and their progeny consisted of 187 red- spotted and 63 green- spotted salamanders. Propose a hypothesis to explain these results. You should show how a color is controlled. What is dominant and what is recessive? State what happens in the F1 with the use of appropriate symbols. What is your prediction for the F2 generation?

Step 1
All the progeny were red-spotted, indicating that red (G) is dominant over green (g). ** Show more…

You have crossed two clawed frogs, one is albino and the other is colored normal. The resulting tadpoles in the F1 generation were all normal colored. F1 frogs were crossed, and the F2 Generation consisted of normal colored frogs and the albino frogs at a ratio of 3:1. Which allele is dominant and which is recessive? What are the genotypes for the original parents

Suppose you identify a new gene in mice. One of its alleles specifies white fur. A second allele specifies brown fur. You want to determine whether the relationship between the two alleles is one of simple dominance or incomplete dominance. What sorts of genetic crosses would give you the answer? On what types of observations would you base your conclusions?
