The endocrine system acts through chemical messengers called- -
3241004551 [841]


The best answer is D.

Hormones are chemical messengers  secreted mostly into blood and also extracellular fluid by specialized tissue of the endocrine system and affect the functioning of other tissues or cells.

Most hormones circulate in blood and come in contact with essentially all cells, but a particular hormone will only affect a limited number of cells, which are termed as target cells to that hormone.

A target cell responds to a particular  hormone because it bears receptors for that hormone.

For example the red blood cells have receptors for the  hormone called insulin which is produced by the pancreas. The red cells are able to take in glucose  when their receptors bind to insulin.

Red-green color blindness in humans is inherited as an X-linked recessive trait. Usually, heterozygous females are not colorblin
Maksim231197 [3]

Answer:

The mentioned characteristics of variability are witnessed because of the phenomenon known as X chromosome inactivation in heterozygous females. As females possess two X chromosomes, they actually should not possess any color blindness.  

The phenomenon of X-chromosome inactivation takes place in a random manner at the time of embryo development. During this only one X chromosome is inactivated. If the chromosome comprising the defective gene is inactivated, the individual will possess normal vision.  

If the chromosome comprising the usual gene gets inactivated than the individual will be color blind. In the given case of female, X inactivation took place in one eye. The inactivation of normal alleles has taken place and thus she possesses normal vision with one eye and is color blind in the other eye.
