I Updated can I have help please

Explanation / Answer

3) The inheritance seen is autosomal dominant mode. This is because both makes and females are equally affected which rules out sex linked inheritance. Further, there is no alternation of generations which is characteristic of autosomal recessive inheritance.

4) The genotype of individual 1 is homozygous normal.

5) Individuals 3 and 4 are both heterozygotes. This can be deduced from the fact that both of them are affected, but one of their offspring is normal.
