Exam 5: Chromosomes and Inheritance

Albinism is a recessive disorder in which the skin and hair fail to produce pigment. The following question(s) ask you to evaluate the pedigree chart shown here in which "N" is the allele for normal pigmentation and "n" is the allele for albinism. The shaded circles for Deirdre and Shannon represent the only individuals expressing the disorder. -What was the probability that Deirdre and Geoff's first child would express the albino trait?

Define Mendel's law of independent assortment.
