Genetic variability is the tendency of individual genetic characteristics in a population to vary from one another.
A reduction in population size can lead to a loss of genetic diversity, limiting the gene pool available for natural selection. This reduction in genetic variability can decrease the ability of a population to adapt to changing environments or withstand diseases. This is known as a genetic bottleneck.
i don't know :P <---- This guys an a**hole. Its to promote genetic variability among offspring. (A)
Substitution mutation can increase genetic diversity within a population by introducing new genetic variations. This can lead to different traits and characteristics, potentially increasing the overall genetic variability of the population.
Recombining of genetic information (crossing over) during prophase I of meiosis results in every chromosome being a combination of the person's mother's and father's genetic information. Recombination of genetic information in an offspring takes place at the time of gametic union forming the zygote. The genetic variability depends on the extent of heterozygocity present in the population of that species. Role of crossing over is limited to the extent of frequency of genes present in an individual to produce variety of gametes.
The primary source of genetic variability in prokaryotes is through horizontal gene transfer mechanisms such as transformation, transduction, and conjugation. These processes allow prokaryotes to acquire new genetic material from other bacterial cells or environments, leading to genetic diversity within populations.

S. fimicola can lead to genetic variability within a population through sexual reproduction, which involves the exchange of genetic material between individuals during mating. This process can generate new combinations of alleles, leading to increased genetic diversity in the population. Additionally, mechanisms such as mutation and genetic recombination can further contribute to genetic variability in S. fimicola populations.

The purpose of synapsis is to increase genetic variability
There is no genetic variability since the offsprings are not very different from their parents.
