What kinds of populations are affected by genetic drift?
Genetic drift occurs in all finite populations. However the effects of drift are more pronounced in smaller populations than in large ones. Meanwhile, even though they are more present in smaller populations, the drifting is more likely to occur in larger populations because of the larger number of different genetic combinations present. Throughout evolution of populations, genetic drifting effects all types of population sizes, though it is more likely in larger populations but more present in smaller populations.
What type of cell reproduction is more likely to increase genetic diversity?
Sexual reproduction is most likely to increase genetic diversity.
What is a sentence using the word genetic drift?
Once a single species is physically separated into two or more populations, genetic drift often permanently separates those populations into distinct species no longer able to interbreed, even if they should later again intermingle.
Would a population of 10 individuals or 100 individuals be more vulnerable to genetic drift?
10, because it's easier to detect the ratio of 10 than the ratio of 100
What is a genetic drift and when does it occur?
Genetic drift is the spread of specific random variations throughout the gene pool in the absence of specific selection pressures. There's always random variation in the population, but there aren't always changes in the environment for the population to adapt to. So natural selection, in stead of moving the population towards adaptation, might select from that random variation to move 'sideways', as it were, to a state that's equally well-adapted to the environment as what came before, but different. As random variation may produce many variants that are, more or less, equally well-adapted to their environment, the direction of evolution that results is more or less random. Because variations may spread throughout small populations faster than throughout large populations, and because a large gene pool has a stabilizing effect on the spread of variations, small populations drift faster than large populations.
Genetic drift is more likely to occur in large population true or false?
false... its likely to occur in small population
Why is genetic drift more likely to occur in smaller population?
As you have less variety, eventually, people will have to breed with distant relations, therefore creating hereditary diseases.

Genetic drift tells us that individuals with traits that are favorable will be more likely to survive and have more offspring?
False
What types of population does genetic drift affect?
Isolated populations can lose genetic diversity through genetic drift. This is because some alleles can be lost by chance. Many more homozygous individuals are likely.
What is the similarity between natural selection and genetic drift?
No. Genetic mutations lead to changes in the gene. This results in a (possible) new allele. Genetic drift is the change in frequency of an allele in the population due to chance. The smaller the population the bigger the chance on genetic drift (like it is more likely to coin flip 10 heads in a row then 1000 heads) while on the other hand the bigger the population the bigger the chance new alleles will be created by mutations.
How would genetic drift affect a population in genetic equilibrium?
because genetic modifications have more allieles than the first and second generation youre welcome:)
Genetic exchange between two arms of a chromosome pair is more likely to occur if the distance between the genes is great It is called?
crossing over
What type of cell reproduction is more likely to increase genetic diversity?
Sexual reproduction is most likely to increase genetic diversity.

What happens when Rare allele is in a small population?
The smaller the population the greater the frequency the allele will increase. When the Old Order Amish came to America in 1744 it was a husband and wife. One of them was a carrier for a recessive genetic mutation. As time went on and inbreeding occured because of the small population more and more children were born with the genetic disorder.
What effect does a bottleneck have on the allele frequency of a population?
A bottleneck can lead to a significant reduction in the genetic diversity of a population, causing certain alleles to be lost and others to become more common. This can increase the frequency of rare alleles and result in genetic drift, potentially leading to an increase in genetic diseases or reduced fitness in the population.
