Solution-Carriers of a recessive trait

Fred and Ethel have normally pigmented skin but they have a child who is an albino. They are carriers of a recessive trait = heterozygotes.  STOP – READ THAT LAST SENTENCE AGAIN – YOU ARE GOING TO NEED IT TO ANSWER THE SECOND QUESTION. Use A or a for alleles.

  • What is the probability that they will produce a second child who has normally pigmented skin?
  • What is the probability that they will produce a second child that is a carrier for albinism?
