Filled-in symbols in the pedigree that follows designate individuals suffering from deafness. a. (2 points) Study the pedigree and explain how deafness is being inherited. b. (2 points) What is the genotype of the individuals in generation V

According to the pedigree, It is clear that the F1 generation is not affected but their offspring are affected in F2, which explains that the deafness presented with the pedigree is recessive. It should be an Autosomal recessive inheritance as it is found in both male and female offsprings.

As it is found that the parents are affected in 5th gen and 6th generation but their offspring are not affected which means there must be more than one genes controlled this disorder

B. In 5th generations mentioned above offspring is unaffected but parents are affected, to find the genotype of the individual let assume there are two genes responsible for it A and B, and mutation in any one of them can result in deafness.

So in IV generation Individuals 5 and 6 have genotypeAAbb and aaBB; both are deaf.

gametes:- Ab & aB.

So, the genotype of all offsprings will be AaBb means all are normal.
