    Use the information below to answer questions 1-2. Leather back turtles (Dermochelys coriacea) lay 50 eggs per clutch on soft sand beaches. Let us assume that the first and second cleavage within the developing eggs is controlled by the presence of a single pair of codominant alleles, CA and C Full cleavage and development to maturity will occur if an offspring bears alleles in the heterozygous (CAC) condition. However, there is only 18% cleavage penetrance if C Cappears in the...

    Assume that tail length in mice is a quantitative trait involving two genes, each with 2 alleles. One allele at each gene contributes to long tails, the other allele at each gene does not (small tails). The genes are located on different autosomes. Mice with 0 contributing alleles have tails that are 4 cm in length; mice with tails with 4 contributing alleles are 12 cm in length. Determine the phenotypic ratio from an F2 from a true breeding parent...
