Facial dimples and free earlobes are both considered dominant human traits. What are the expected phenotypes of the offspring of a female with dimples and free earlobes (DDFf) and a male with no dimples and attached earlobes (ddff)? a 75% with dimples and free earlobes and 25% with no dimples and attached earlobes b 50% with dimples and free earlobes and 50% with no dimples and attached earlobes c 50% with dimples and free earlobes and 50% with dimples and attached earlobes d 75% with dimples and attached earlobes and 25% with no dimples and free earlobes

As mentioned in the question,Facial dimples and free earlobes are both considered dominant human traits. We have been asked that what is the expected offspring of a female with dimples and free earlobes (DDFf) and a male with no dimples and attached earlobes (ddff).

Lets cross them:

P1: DDFf X ddff

Gametes: DF: Df : df: df

Offspring:

50% : Dfdf: with dimples and free earlobes

50%: DdFf: dimples and attached earlobes

You can see the cross for a better understanding in attached image that how i created a punnet square to get the results of the cross.

Hope it helps!
