Finger mid-digital hair (M) is dominant over the recessive trait of no mid-digital hair (m). Freckles (F) is dominant over the recessive trait of no freckles (f). (It is important to note that this example of mid-digital hair and freckles cannot be explained with simple genetics, but for the purpose of this question, assume that it can.) A woman that is heterozygous for freckles and has no mid-digital hair is married to a man with no freckles that is heterozygous for mid-digital hair. The couple is expecting a child. Draw a Punnett square of this cross.  What is the probability that their offspring will have mid-digital hair?   What is the probability that two offspring in a row will have no freckles?  What is the probability of two offspring in a row having mid-digital hair and freckles?
