How might genetic drift alter the diversity of a population?
Genetic drift basically is the reduction of genetic diversity where certain genes are selected through random chance. Founder or bottleneck events are the major ones. Those certain genes may or may not be beneficial.
Why genetic drift affects the diversity of organisms in a small population?
Genetic drift in small population results in fixation of a gene or loss of gene affecting only that particular population . It has no direct effect on diversity of organisms .
Was Genetic drift a factor in the diversity and evolution of humans?
False, was.
How would genetic drift affect a population in genetic equilibrium?
because genetic modifications have more allieles than the first and second generation youre welcome:)
Which evolutionary mechanisms could affect allele frequencies in a population being maintained in captivity?
natural selection, genetic drift, and mutation
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.
One consequence of genetic drift is?
Genetic drift usually only has effect on the genetic diversity of small populations of a species. Often times, genetic drift can greatly reduce the diversity of a population if a significant percent of members of the population leave by a chance event (as opposed to natural selection.) This means that their alleles for various genes leave with them. Genetic drift does not always effect genetic diversity. Most of the time, it is the allele frequency that is affected by genetic drift. For example, if there are 60 long-finned bass and 40 short-finned bass living in a pond, the gene frequency ratio is 3:2. If 25 short-finned are fished out, the allele frequency is now 4:1. If all or most of the members of a population carrying a specific gene were removed from the population because of genetic drift, that would effect the genetic diversity.
Why does genetic drift decrease the genetic diverstity of a population?
If I'm not mistaken genetic drift is the random change in the genome of a population over time. This being said it would be possible that this random changing could eventually remove certain diversity from a population.

It is believed that genetic drift was a factor in the diversity of humans?
true

What would decrease genetic variation in a population?
When there is low genetic variation in a population the species produced are unlikely to withstand diseases.
Which population is a subject to genetic drift?
A large population..
A random change in a population's allele frequency?
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
What does not add new alleles to a population gene pool?
