Problem:
Dominant mutation (Sb) in the Sb+ gene results in flies with stubble bristles.
A dominant mutation (Ser) in the Ser+ gene results in flies with serrated wings.
Stubble-bristled flies with normal wings are mated to flies with normal bristles, but serrated wings.
Both Sb+ and Ser+ loci are on the third chromosome.
Required:
Question: What would be the expected progeny and what would be their proportions (ratios)?
Question: Give phenotypes and phenotypic ratios with an explanation.
Any help would be greatly appreciated!
