2. Suppose that you and 19 of your classmates (giving a final population of 10 males and 10 females) are on a cruise, and your s
Trava [24]

Answer:

0.25%

Explanation:

20 people start the new population. So there are 20 genes or 40 alleles for the recessive disorder phenylketonuria. 2 out of 40 alleles are recessive for the condition hence frequency of the allele = 2/40 = 0.05

Frequency of the allele does not change when the population increases so it is in Hardy-Weinberg equilibrium. According to it, if q is the frequency of recessive allele, q² = frequency of the recessive condition

Here, q = 0.05 So,

q² = (0.05)² = 0.0025

In percentage, it is 100 * 0.0025 = 0.25%

Hence, incidence of phenylketonuria in the new population is 0.25%

Which letter in Figure 1 represents meiosis? Why?
SSSSS [86.1K]

The letter D in Figure 1 represents meiosis, while letter A represents mitosis. Meiosis is a reductional cell division.

Mitosis is a type of cell division where a parent cell divides to produce two genetically identical daughter cells (in this case, diploid cells).

Meiosis is a reductional cell division where a parent cell divides twice to produce four daughter cells having half of the genetic material.

Meiosis occurs in germinal cells, while mitosis occurs in somatic (body) cells.
