nlexa [21]

Question in English:

A female carries a recessive lethal gene (l) on one of her X chromosomes, and a normal dominant allele (L) on the other. What is the sex ratio to be expected in this woman's dependency if she marries a normal man?

Answer:

2/3 females

1/3 males

Explanation:

Females have two X chromosomes (XX) and males have an X and a Y chromosome (XY).

The genotype of the female is XLXl. The genotype of the male is XLY, since he is normal.

The possible genotypes are:

<u>                            XL                  Xl</u>

<u>XL</u>                     <em>XLXL             XLXl</em>

<u>Y</u>                       <em>XLY               </em><em>XlY</em>

<em />

All female offspring will be normal as they will always have one normal copy of the X chromosome from their father.

50% of the male offspring will be normal, but 50% will inherit the lethal gene from their mother.

Because the allele is lethal, that means XlY males will not be born.

That means 2/3 of the children will be females, and 1/3 will be males.

How does human evolution relate to the sensibility of disease
igomit [66]
Human evolution known to be a process in which species adapt to certain conditions of life, and in the battle of life and death, they are forced to become stronger in order to survive in the world. Diseases have always been present during the evolution, acting themselves as a natural selector-the weaker organisms get sick and die.
