What genetic ratio do these following numbers best represent

What genetic ratio do these following numbers best represent 365, 158 and 111

Solution

Answer:

The following number represent the Genotype ratio.

365: 158 :111

AA: Ab: bb

total : 634

AA (Homozgous dominant )= 365/634 = 0.575 = 57.5%

Aa (Heterozygous dominant)= 158/634= 0.249 = 24.9%

aa (Homozygous recessive)=   111/634= 0.175 = 17.5%

As genotype is different but phenotype will be same in case of AA and Aa = 57.5 + 24.9

                                                                                                           = 82.4

                                So,    82.4 : 17.5

                                      = 13:3 ratio
