Complete individuals joining a population are an example of

get all of the one

Explanation:

Which of the following can evolve?

populations

population is defined as:

all individs of same species located in a given geographic region

allele frequency

relative proportion of a given allele in a population

interaction of genes and environment produces a specific:

phenotype

The gene pool for a particular gene is made up of

ALL genes that occur in population

In a very small population of birds, assume 5 out of 20 alleles are the type that code for blue feathers. What is the allele frequency of the "blue feather allele" in this population?

.25

evolution can be defined as

a change in the genetic makeup of a population over time.

Populations of organisms are constantly evolving, which means they are always

changing

Within a large population, if no mutations occur, no migration occurs, all matings are random, and each individual has an equal chance of reproducing, which of the following will probably happen?

no evolution will occur

In the context of evolution, equilibrium means

no change in allele frequency

In an equilibrium population

allele frequencies do not change

According to the Hardy-Weinberg principle, if 75% of the alleles in the gene pool are A1 and 25% are A2, what is the proportion of individuals with genotype A1A2 in this population?

.375

A population carries two alleles for a trait in which T is dominant and t is recessive. In the Hardy-Weinberg equation, 2pq represents the

proportion of heterozygous individuals.

A population carries two alleles for a trait in which T is dominant and t is recessive. In the Hardy-Weinberg equation, p2 represents the

proportion of homozygous dominant individuals.

A population carries two alleles for a trait in which T is dominant and t is recessive. In the Hardy-Weinberg equation, q2 represents the

proportion of homozygous recessive individuals.

Imagine that one of the original four mice that escape from a research lab is blind due to a genetic defect. If the escaped mouse breeds and most of the mice born in subsequent generations are blind from birth, this is most likely a case of

the founder effect

Which of the following can cause evolutionary change in a small population?

genetic drift

Which of the following is most likely to experience genetic drift?

A population of endangered birds that includes only five individuals

Inbreeding is defined as

sexual reproduction among closely related individs

From an evolutionary point of view, what important process occurs when a young male baboon leaves the troop that he was born in to join another troop?

gene flow

Zoos often loan animals to other zoos for breeding purposes. From an evolutionary standpoint, what is the benefit?

increases genetic diversity

The 30,000 elephant seals alive today are genetically very similar due to

bottleneck effect

Habitat loss, natural catastrophes, and/or excessive harvesting of a species often result in

population bottlenecks

Which of the following mutations would increase evolutionary fitness?

One that increases the frequency of successful reproduction

The process by which allele frequencies are altered in a population due to chance is called

genetic drift

is correct hope this   also i learnd this in middle school
