6. In solving problems 1-4, you made some predictions of TRCs based on the genotypesof the individuals involved. Suppose we could measure the TRCs for some people withthose genotypes and found the actual values to be different from those predicted by yourcalculations. How would you explain these discrepancies? EXTEND YOUR UNDERSTANDING WITH ADDITIONAL TRC PROBLEMSTotal fingerprint ridge count exemplifies a polygenic inheritance pattem. Penrose (1969)and others have suggested that a minimum of seven gene loci contribute to TRC, but afour-locus model is hypothesized in the problems that follow. Thus, AABBCCDDrepresents the genotype for maximum ridge count and aabbccdd symbolizes the genotypefor the minimum ridge count. Assume that each active (dominant) allele adds 12 ridges tothe TRC of the male and 9 to the TRC of the female and that having the genotypeaabbccdd produces a baseline TRC of 80 for males and 70 for females. (one answer isgiven below to calify any issues with the instructions).1.

Write the genotypes of both parents (parental cross) who are heterozygous for all fourgenes (tetrahybrid cross).Write the genotype of the child (from the cross above in Question 2) who has themaximum number of active alleles possible.a.
