Since the colorblindness is located on the X chromosome, the man must have inherited his colorblindness from his mother.
<h3>X-linked traits</h3>
Women are XX while men are XY.
Also, the X chromosome in XY always comes from the mother.
Since the man is affected for colorblindness but his brother is not, it means that only one X chromosome of the mother is affected while the father can be affected or otherwise.
Assuming the father is free from colorblindness and the allele is represented by c:
x
Thus, the man's genotype is and it comes from the mother.

Answer:
Because either humans are passing away quickly or there are a lot of child births (Maybe even both)
Explanation:
<span>My pea plant has an unknown genotype for flowers, whether it has two dominant traits for white flowers (WW) or one dominant and one recessive (Ww) leading to white flowers; therefore I am doing a testcross in order to determine the genotype of my pea plant. The best plant to do this with is one that has a phenotype of purple flowers (ww) - that is, it is homozygous for the recessive trait.
If I use a homozygous recessive plant, I know exactly what its genotype is. I don't have to worry about whether it's got one or two dominant alleles; I know that at least half of my alleles are going to be the recessive w.
This makes identifying the offspring's genotype very simple. If I find that the offspring have at least some purple flowers among them, I know that my original plant had to be Ww; that is it had to have one dominant and one recessive allele for the flower color gene. If, however, all of the offspring are white flowers, I know that my original pea plant had both dominant alleles (WW).</span>

Explanation:
To find the speed/velocity of an object, you can use this formula :
v = displacement / time
Plugging in our values....
v = 65 m / 10 s
v = 6.5 m/s
Hope this helps! Best of luck <3
