Imagine you had a bunch of bacteria which grow on glucose. Through a genetic mutation one of them gains the abilitiy to digest galactose also. You might think that sugar is sugar and anyhow, there's always enough glucose for everyone. Generally speaking you're right, and the mutant invests more energy than his colleagues to maintain his mutation, which is a disadvantage under normal conditions.
But now imagine an evil scientist, who transfers the bacteria to a galactose-medium: All will starve except mutant, which will grow faster without having neighbours to share his meal with. So the Mutation helped the species to survive.

So a higher amount of genetic variation will ensure that there is a lot to choose from, breeding wise.

∙ 11y agoA population with high genetic diversity or more genetic plasticity i.e. sexual reproduction, less inbreeding ect., the more likely the population can adapt and survive in changing conditions. The more genes there are in a population, the higher the chance some of them will help an individual survive in conditions that may kill off others. And individual that survives will reproduce more, and these helpful genes can spread throughout the population.

How does migration affect the genetic equilibrium of a population?
Migration affects the genetic equilibrium of a population by maintaining it.
How would genetic drift affect a population in genetic equilibrium?
because genetic modifications have more allieles than the first and second generation youre welcome:)
How does sexual reproduction affect a population's genetic variation?
It affects genetic variation, because the two parental organisms might have different alleles for each gene. For example, say a blonde eyed male and a brown eyed female reproduced, and the trait for brown eyes is dominant (Bb) and the blue eyes are recessive (bb). If they mated they would have the genotypes: Bb, and bb. Therefore, increasing variation
Which evolutionary mechanisms could affect allele frequencies in a population being maintained in captivity?
natural selection, genetic drift, and mutation
How might the presence of a chemical mutagen affect the genetic size of a population over time?
It affects the population because mutations can be deadly and they're passed down from one generation to the next making the population shrink.

How does genetic variation affect the type of traits of adaptations in the individuals of a species?
Variation in and of itself does not affect the traits seen in the overall population. This is because gene frequency and subsequent changes in phenotype generally occur only when the phenotype is "selected" for or against in a population. Granted increased genetic variation is the potential for change, however just as in physics potential has to be acted on for change to occur.The population of a species represents it's entire gene pool. The Hardy-Weinburg Principle states that the frequency of a gene remains the same as long as it is neither selected for or against.Smaller populations can change rapidly due to genetic drift and isolation (which is more of a twist of random probability than selection, like getting heads ten times in a row tossing a penny) selection translates into change in a larger population.
How does migration affect the genetic equilibrium of a population?
Migration affects the genetic equilibrium of a population by maintaining it.
Why variation in a species gene pool contributes to it's survival in a constantly changing environment?
Variation within the species would mean that individuals are likely to react differently to environmental change. This means that they may not all have a negative reaction, and therefore the species is more likely to survive.A large population is also important in limiting the risks of environmental influence - as changes may not reach or affect the entire population.

What is the relationship between sexual reproduction and genetic variation?
In sexual reproduction, two parents combine their geneticmaterial to form a new organim. Meanwhile, genetic variation can give the new organism a helpful trait or unhelpful trait that would affect its life and how it could life in a certain enviornment.
