Answer #1

The probability that their next child affected is 1 in 2 as the disorder is autosomal dominant which means altered copy of one gene is sufficient to cause disease. Considerinf father with disease and normal mother, their every child has 50% risk of getting disease. So option b seems correct and option c n d are incorrect.

option a seems incorrect because in autosomal dominant inheritance their will b no carrier

    2. Achondroplasia is a short-limbed dwarfism that is inherited as an autosomal dominant disease. The mutant allele that causes this form of dwarfism (D) is dominant to the normal allele at this location (d). Individuals who inherit 2 alleles for dwarfism (DD) typically have a very severe form of achondroplasia that causes extreme shortening of the bones and an underdeveloped rib cage. These individuals are usually miscarried or stillborn. Tom and Vonna both have achondroplasia (but each of them has...
