A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was six

Degger [83]

Answer:

1/4.

Explanation:

The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.

The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.

So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.

What would happen if gametes were not haploid?

Yanka [14]

If haploid didn't occur on gametes, it would occur on diploid, which would increase the number of chromosomes, and the child would have a lot of them.
So, what would happen if gametes were not haploid is that B. the offspring would have double the number of chromosomes it is supposed to have.
