In humans, cystic fibrosis and albinism are both inherited as independently assorting autosomal recessive traits. Use f to represent the recessive allele for cystic fibrosis and F for the allele for the unaffected condition. Use A to represent the dominant allele for normal melanin and a for the recessive allele for albinism. A man is albino and heterozygous for cystic fibrosis. His wife has the unaffected phenotype for both traits, although her father had cystic fibrosis and her mother is albino. 4a. What is the genotype of the wife 4b.What is the probability that a child of this couple is albino and has cystic fibrosis? 4c.What is the probability that a child of this couple is a girl who is albino and has cystic fibrosis? 4d.What is the probability that a child of this couple is normal for both traits?

The law of independent assortment was first observed by Gregor Johann Mendel in 1865 during his studies of genetics. This law describes how different factors called genes independently separate from one another when reproductive or germ cells develop. This law states that different genes and their alleles are inherited independently within sexually reproducing organisms. The Chromosomes are separated into multiple gametes during meiosis. The factor or genes linked on a chromosome can rearrange themselves through the process of crossing-over.
