I believe the correct answer is a. mutations.

Answer:

Option A, Mutation

Explanation:

Mutation can cause the variation in a defined genetic set of an organism there by producing allele of varied types. However an allele is a variant gene. For example

A male flower has following allele – WW (representing dominant white color flower)

A female flower has following allele – ww (representing recessive blue color flower)

If these two flower mutate either through natural processes or though the mating, new species of flower with a different and unique genotype (allele set) is formed

for example a grey color flower with unique allele set - Ww

Alleles are carried on chromosome which expresses certain trait, variation in genotype also brings variation in allele's trait expression.

Hence, option A is correct

Sloan [31]

A human fetus develops at the mother’s body temperature. At birth, most newborns experience a drop in temperature, and their bodies must quickly do something about it. What they do is the same thing a hibernating mammal does as it rouses itself from its winter "snooze." During hibernation, an animal’s body temperature is low. In order to move about and take care of itself once awake again, the animal that has been hibernating must raise its body temperature. (William k. Purves et al., life: the science of biology) The definition is the primary pattern of organization in this passage.

This passage is explaining the process of hibernation and its importance in the animal life cycle.

Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another. true
devlian [24]

The given statement "Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another." is False.

<h3>What is gene flow?</h3>
  • Gene flow refers to the processes by which genes are transferred from one group to another.
  • Gene flow, which is a term used more frequently in anthropology, refers to the allelic change brought on by human movement.
  • Gene flow would reduce the isolation that could lead to speciation by increasing population similarity and reproductive kinship.
  • Gene flow significantly slows down speciation by recombining the gene pools of the groups and therefore repairing the growing variations in genetic variation that would have otherwise resulted in full speciation and the creation of daughter species.

What's the difference between genetic drift and change due to natural selection?
JulijaS [17]

Answer:

Genetic drift does not require the presence of variation.

Explanation:

Genetic drift is the random changes to the frequency of an allele in a given population.

Natural selection is the process whereby organisms that are well adapted to the conditions in an environment can survive and produce more offspring.

  • Genetic drift does not require variation to occur.
  • It usually occurs even when there is less to no variation.
  • Natural selection occurs when variation is very large.
  • A highly varied gene pool causes natural selection.
