A man with normal vision marries a color-blind woman. Red-green color blindness is an X- linked recessive disorder. They have a
jeyben [28]

Answer: The probability is 100%.

Explanation: The chromosome X is related to gender. A man carries two different chromosomes (XY) and a woman carries two similar chromosomes (XX). The offspring of a couple will inherited:

  • If it is a boy, he inherites the chromosome Y from his father and X from his mother;
  • If it a girl, she inherites X from her father and X from her mother;

In the question, the woman is color-blind, which means she carries the recessive alleles: X^{d}X^{d}

The man, on the other hand, is normal, so his X-linked genotype will be: X^{D}Y.

Now, since they have a daughter, she inherited her double X from each of her parents, which means she inherited one X^{d} from her mother and one X^{D} from her father.

So, the daughter's genotype can only be heterozygotic  X^{D}X^{d} in other words, the probability is 100%.

How many mudskippers does it take to defeat a man?
Marina86 [1]
Boleophthalmus boddarti is detritivorous, while others will eat small crabs, insects, snails and even other mudskippers. Digging deep burrows in soft sediments allows the fish to thermoregulate, avoid marine predators during the high tide when the fish and burrow are submerged, and lay their eggs.
