Question

What would happen if fertilization no longer occurred in a species that reproduces sexually?

A. The species would increase in number.
B. The species would decrease in number and eventually die off.
C. Individual variation within the species would increase.
D. Disease would destroy the species.

Answer 1

B. The species would decrease in number and eventually die off.

Step-by-step explanation:

Fertilization is one of the stages of sexual reproduction, in which sex cells or gametes unite to form the zygote or egg cell. The zygote passes through many cell divisions giving rise to an embryo, which will develop into a new being.

If fertilization does not occur in a sexually reproducing species, that species would decrease in number and die over time. This is because there would be no birth of new individuals.

Answer 2

B. The species would decrease in number and eventually die off.

If you think about it, if human beings couldn't have children, what would happen? There would be less and less of us, and eventually we would die off. It is the same with any sexually reproducing species.
