The greatest degree of genetic variation would be found in an offspring resulting from sexual reproduction.

<u>Explanation:</u>

Asexual reproduction produces very less variations. Asexual reproduction requires only one parent and thus the offspring would be very similar to the parent. The chance of variations in offspring is very less.

But the case of sexual reproduction is different. Sexual reproduction involved two parents and each parent contribute equal amount of genetic material to the progeny.

Some characters of the offspring will be like one or the other parent and some characters will be a combination of the characters of both parents . Such a combination produces variant offspring.

(SOLVED!!) Which of the following examples best describes an organism's niche?
Vikentia [17]

Given what we know, the example that most appropriately described an organism's niche is that Panda bears have a very limited diet, primarily feeding on bamboo in their environment.

<h3>What is a niche in ecology?</h3>
  • It is described as a role filled by an organism.
  • This role or trait is specific to the environment of the organism.
  • It describes the adaptation of the organism to the resources present.

Therefore, given the definition of a niche as an adaptation or role filled by an organism that is specific to their environment, we can confirm that the example with the panda bears fits this description since they will only eat bamboo, being the <u>only bear species to not be carnivorous</u>.

True or False: The following example populations meet the basic requirements of Hardy-Weinberg equilibrium. a. A small, isolated
Setler79 [48]

Answer:

Only option D is TRUE. The rest are FALSE.

Explanation:

In Hardy-Weinberg equilibrium, there is virtually no change in the frequency of alleles and genotype, in a population, meaning there is a genetic equilibrium in that population which shows no real evolutionary change has occurred. According to the , several conditions must be met before such equilibrium can be said to occur in a population, these requirements or conditions are:

1. There must be an unrestricted random mating

2. Mutation that results in the change of gene is absent

3. The population size must be large enough

4. Absence of migration,i.e. no movement of members out of a population or into a population

5. No natural selection

Now let’s take a  at the example of populations given, stating whether they meet the above listed conditions or not

For option A, which is “A small, isolated population of seals living in a stable environment with no genetic mutations” this is False, a small population size of seals is more likely to have its allele frequencies changed by random fluctuations compared to a large population size of seals. This does not satisfy condition number 3 listed above.

Option B, “A large population of fish where females mate with males based on size” is False. It does not satisfy condition number 1 listed above. In this population example, there is restricted random mating.

Option C “A population of birds with no genetic mutations that often mate with members of neighboring bird populations” is False. It does not meet condition 4, because there is exchange of genes with other populations that might have different allele frequencies.

Option D “A large, isolated population of squirrels that lives in a stable environment, has no genetic mutations, and mates randomly” is True. This meets all conditions listed above.

Option E “A large population of spiders that experiences immigration from a second nearby population” is False. This does not meet condition 4.
