2. Total fingerprint ridge count (TRC) exemplifies a polygenic inheritance pattern. AABBCCDD represents the genotype for maximum ridge count; aabbccdd shows the minimum ridge count. Assume that for males each dominant allele adds 12 ridges to the TRC of the male, but adds 9 to the TRC of the female. The genotype aabbccdd produces a baseline TRC of 80 for males and 70 for females. Suppose two parents are heterozygous for all four genes: a. What is the genotype of their child who has the maximum number of active alleles? Minimum number of active alleles? b. What are the TRCs for the parents and their child (assume the child is male). Mom: Child: c. Calculate the probability that the heterozygous parents would produce a child with the minimum number of active alleles.
