Dear Student,

Let us consider that the Heterozygous Man has Gamete for dimples as
' Dd '
and , The woman is Homozygous with gamete ' dd
'
The mating between these two individuals will produce FOUR
offsprings with the following gametes -

Therefore , The probability of Having Dimples of their First Child
is - 2 out of 4 (Dd and Dd)
That is 50%
