The correct answer is D. increases levels of greenhouse gases

Explanation

Greenhouse gases are a group of gases present in the atmosphere such as carbon dioxide, methane, ozone, water vapor, chlorofluorocarbons, among others, and what they cause in the atmosphere is a greenhouse effect, that is, they trap two thirds of the sun's rays and retain them within the Earth's atmosphere. These gases are thereby natural processes of the earth; however, with the increase in emission of gases by combustion of fossil fuels some greenhouse gases have increased their percentage in the atmosphere, especially carbon dioxide. This causes the temperature increase in the earth's atmosphere by the retention of solar rays in greater quantities. So, the correct answer is D. Increases levels of greenhouse gases.

Una mujer lleva en uno de sus cromosomas X un gen letal recesivo (l), y en el otro alelo dominante normal (L). ¿Cuál es la propo

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:

XL Xl

XL XLXL XLXl

Y XLY XlY

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.
