SEXUAL REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Describe the amount of genetic variation in organisms that reproduce asexually
A
Involves egg and sperm
B
requires male and female
C
reduces the variation in offspring
D
increases the variation in offspring
Explanation: 

Detailed explanation-1: -Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly.

Detailed explanation-2: -Asexually reproducing organisms spend fewer resources for the same reproductive output, meaning their populations grow and expand faster than sexually reproducing ones. On the other hand, asexual populations have reduced genetic diversity and, hence, lower adaptability to changing environments.

Detailed explanation-3: -Asexual reproduction generates offspring that are genetically identical to a single parent.

Detailed explanation-4: -Asexually reproducing parental organisms are identical to offspring. Therefore, it does not allow genetic diversity in the population. It limits the evolutionary process. Genetic variation is only possible in an asexually reproducing population when a random mutation occurs.

Detailed explanation-5: -And not only does asexual reproduction lead to higher rates of genetic diversity, it also is two times more efficient than sexual reproduction.
