Answer:
40 individuals
Explanation:
The homozygous recessive percentage is equal to q2.
Recessive genotype frequency, q 2 is 1/1000000 = 0.000001
therefore, q =
=
= 0.001 = allele "a" frequency
and p + q = 1, thus, p = 1 – q = 1 – 0.001 = 0.999
thus, the frequency of allele a = q = 0.001 and the frequency of allele A = p = 0.999
Carriers are heterozygous and are equal to 2pq.
So, 2pq = 2 x 0.999 x 0.001 x 20,000 = 39.96 (round of to 40)
Hence, 40 individuals will be expected to carry the recessive allele.

The Answer is A. The presence of sodium potassium pumps has nothing to do with water moving in and out of cells.
A single gene disorder is one that's known to be caused by a single gene. Multiple gene disorders, however, can be caused by multiple gene combinations and other factors. Dominant genes are always expressed in the offspring, while recessive genes are only expressed if the offspring recieves the recessive gene from both parents. Sex-linked genetic disorders occur most often in men, and are caused by a single-gene disorder gene being on the X chromosome but not the Y, so that the offspring needs only one recessive gene to have the trait/disorder.
