Homework Answers
1. The trait is arecessive trait. This is because none of the parents of the off spring having the trait shows the phenotype of the trait.
2.I-1 and I-2 are both heterozygous and are the cariers of the trait.
3. The probability that the next child of III-5 and III-6 will be affected is 25%
4.The chance that iv-1 will have a child with affected trait if he marries some one with the trait is 50% because iv-1 is heterozygous
