Q. Even though it is thought that there are actually 7 loci involved in producing fingerprint ridges for the next two problems we will utilize a simpler 4 locus model. The loci are named A.B, C and D. There are two alleles at each locus. A capital letter indicates a dominant allele and a lower case letter indicates a recessive allele. Also the alleles have different effects in males and in females. A male with the genotype aabbccdd would have a total ridge count (TRC) of 80 and a female would have the TRC of 70. In contrast, each dominant allele in an individual’s genotype contributes 12 ridges to the TRC in males and 10 ridges to the TRC in females.

What would be TRC for a male with the genotype AABbCcDD? For a female?
