The allele for albinism (c) is recessive to the allele
  for normal pigmentation (C). A normally pigmented
  woman whose father is an albino marries an albino
  man whose parents are normal. They have three
  children, two normal and one albino. Give the
  genotypes for each person listed. What will be an ideal response?
 
 

Question 2

In humans, normal skin pigmentation is influenced
  by a dominant gene (C), which allows pigmentation
  to develop. All individuals who are homozygous for
  the recessive allele (c) are unable to produce an
  enzyme needed for melanin formation and are
  therefore referred to as albino. Two normal parents
  produce an albino child. What are the chances that
  the next child will be an albino? What will be an ideal response?
