AABbCcdd x AaBbCCDD 1 Min number of ridge producing allele

AABbCcdd x AaBbCCDD

1 - Min number of ridge producing allele for one child

2 - Max number of ridge producing allele for one child

3 - If child is male, will he have higher or lower TRC count than parent

4 - TRC for male and Female

Solution

When AaBbCcDd mates with an AaBbCCDD type

1 - Min number of ridge producing allele for one child would be 4 (AaBbCcDd) 4 allele are dominant
2 - Max number of ridge producing allele for one child would be 8 (AABBCCDD) 8 allele are dominant

3 - If child is male, he will have higher TRC count than parent as
each dominant allele adds 12 ridges to the TRC of the male and 9 to the
TRC of the female.

4 - TRC for male and Female:
for males genotype aabbccdd produces a baseline TRC of 80 and for males it is 70 (the average TRC is 145 for male and for females it is 126)
