Answer:
a) aaBb
b) Dimples and short eyelashes
c) 50%
d) 25%
Explanation:
Let the gene for dimples be A
Let the gene for eyelashes be B
a) Woman has no dimples (aa) and is heterozygous for long eyelashes (Bb) so her genotype : aaBb
b) Man is heterozygous for dimples (Aa) so he will have dimples and it is already given that he has short eyelashes (bb)
When aaBb X Aabb :
aB ab
Ab AaBb Aabb
ab aaBb aabb
c) Out of the four possible combinations, aaBb and aabb will be born without dimples so this couple has 50% chance to produce a child without dimples.
d) Only aabb will be born without dimples and without long eyelashes so the couple has 25% chance to produce a child without dimples and without long eyelashes.
