Question

In this simulation, you sampled the gene pool without replacing beads in the beaker after you drew each one. Thus, f(A) and f(a) in the gene pool changed slightly after each bead was drawn. For example, if you begin with 50 light and 50 dark beads, the probability of drawing a dark bead the first time is 50/100 = 0.500. The beaker would then contain 49 dark beads and 50 light beads, so the probability of drawing a second dark bead becomes 49/99 = 0.495. Does this make your simulation slightly less realistic? In small natural populations, does one mating change the gene pool available for the next mating, or not? What biological factors must be considered in answering this question?

Explanation / Answer

According to hardy weinberg equilibrium, when mating occour in large population with no disruptive forces, both allelic frequency and genotype will remain constant because they are in equilibrium. This principle distrupt by no. Of forces such as mutation, natural selection, nonrandom mating , genetic drift and gene flow.

Natural selection and nonrandom mating occur due to change in allelic frequency , this occur because certain allele help or harm reproductive success.

Nonrandom mating leads to a genetic drift occur in small population, when allelic frequency grow lower or heigher by chance. Here the main biological phenomenon is genetic drift.

So , the answer is yes one mating change the gene pool for another mating due to no. Of forces.
