In natural selection, what must be true of traits that are passed down through generation?

Radda [10]

Natural selection is the process by which individuals who are best suited to the environment tend to leave (on average) more offspring than others.

Evolutionary changes take place over many generations and through millions of years of natural selection. For the genes to survive, they must be among the strongest.

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%.

Besides distance why can't you see across an ocean to land on the other side

Bogdan [553]

If I recall correctly, I was taught:
The particles in the air (dust, smoke, etc.) increase in density the farther you look. Causing a "fog" effect as you look across large distances. Including shore to shore of an ocean.
