Recessive epistasis: Phenotypes

Not what you're looking for?

Ask Custom Question

A locus in Australian Bearded Dragons is involved in the production of pigment. When heterozygous parents mate, 75% of the progeny are colored and the rest are albino. Another phenotype concerns the specific colors that are expressed such that when two green bearded dragons mate, 2/3 of the progeny are green and the rest are speckled green and purple. The albino dragons cannot express whatever alleles they may have that determine specific color.

When a certain line of green dragons is crossed with a certain line of albino dragons, half of the progeny were green and the other half were speckled green and purple. The green progeny were allowed to interbreed, and 24 eggs were produced. How many of each possible phenotype would you expect to see after they hatch?

How many albinos?
How many greens?
How many speckled?
