Answer:
Purpose: Meiosis is a special version of cell division that occurs only in the testes and ovaries; the organs that produce the male and female reproductive cells; the sperm and eggs. ... Therefore the purpose of meiosis is to produce gametes, the sperm, and eggs, with half of the genetic complement of the parent cells.
Genetic variability is a measure of the tendency of individual genotypes in a population to vary (become different) from one another. Variability is different from genetic diversity, which is the amount of variation seen in a particular population.
Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool. ... Chiasmatal points appear randomly on homologous chromosomes, hence amount of genetic material exchanged in every case/cell could be different.

Answer:
25%
Explanation:
T = Hitchhiker's thumb
t = straight thumb
B = Brown eyes
b = blue eyes
The man's genotype is ttBb
The woman's genotype is Ttbb
Make a dihybrid punnett square to find the possible genotypes of the offspring
ttbb is straight thumb and blue eyes. There are 4 out of 16 genotypes with this phenotype so:
Divide 4 with 16 and multiply by 100 to get the percentage of offspring with that phenotype
4 ÷ 16 = 0.25
0.25 × 100 = 25%
