Question

Which of the following occurs most often in a population when genetic variation and overproduction are present?

Some organisms have a lower reproductive success than others.
Some organisms have a higher reproductive success than others.
Some organisms have no reproductive success.
Some organisms do not have genetic variation.

Answer 1

Overproduction is a natural phenomenon in which the number of produced offspring is higher than the number of individuals the ecosystem can sustain. Thus, competition for limited resources occurs.

Because of the genetic variation, the organisms within a population have different chances to reproduce. Most often, some organisms have a lower reproductive success than others do.

The number of individuals with a high reproductive success is rather low as few males are very successful at passing on their genetic material.

The number of organisms with no reproductive success is also very low, as these "ill adapted" individuals will disappear from the population extremely quickly.

Genetic variation is the amount of differences between individuals. Thus, no organism taken by itself has any genetic variation.

Answer 2

Option B, Some organisms have a higher reproductive success than others.

Step-by-step explanation:

Over production is a scenario where an individual produce more than the normal offspring which enhances the survival rate of the newly born species.

Genetic variation causes genetic evolution which lead to development of individuals that are able enough to cope up with the existing environmental condition.

Both over production and genetic variation are leading to higher rate of survival of a newly borne individual and hence causes higher reproductive success.

Option B is correct
