A man who is a dwarf with achondroplasia and normal vision marries a color-blind woman of normal height. The man's father was si
Kruka [31]

Answer:

None

Explanation:

Assuming the allele for height is T. Since dwarfism is autosomal dominant, a normal height person will be tt while a dwarf person will either be TT or Tt.

Hence, a man who is dwarf but has a normal height father will have a genotype of Tt and an average height woman will have a genotype of tt.

Tt   x   tt = 2Tt (dwarf), 2tt (normal height)

If the allele for vision is represented by B. A normal vision man will have the genotype X^BY while a colour blind woman will have the genotype X^bX^b.

X^BY   x    X^bX^b  =  X^BX^b, X^BX^b, X^bY, X^bY

Since, colour blindness is X-linked and recessive, females need two alleles ( X^bX^b) in order to be affected and none of their daughters posses two alleles.

Hence, none of their daughters is expected to be colour blind with achondroplasia.
