In humans, short fingers(brachydactyly) [B] and woolly hair [W] are dominant over the recessive alleles for normal fingers [b] & normal hair [w]. A man with brachydactyly & normal hair marries a woman with normal fingers & woolly hair. Their 1st child has normal fingers & normal hair.
a- What is the genotype of the man?
b- What is the genotype of the woman?
c- What is the genotype of the child?
d- What is the probability of any child of the above mentioned mating having normal fingers?
