In a Newly Discovered Diploid Animal Species, Tail Length Is

Essay

In a newly discovered diploid animal species, tail length is determined solely by 3 additive gene loci that can have the allele s, which contributes 4mm, and the allele l, which contributes 15mm. Two lines with the genotypes AsAsBsBsClCl and AlAlBsBsCsCs are mated to create the F₁ generation.
a. What is the predicted genotype and phenotype of the F₁ progeny?
b. If two individuals from the F₁ generation are crossed, each phenotypic category will occur in what proportion?
