There will be incidence per population
In terms of male population only it will be
Answer:
a difficult to identify
Explanation:
you can identify this type of fossil by the following-
distinctive, widespread, abundant, and limited in geologic time.
The prefix "poly-" means "more than one" and the suffix "-spermy" is clearly related to sperm. Accordingly, polyspermy is when more than one sperm fertilizes an egg, something that organisms try to avoid.
To avoid this extra fertilization, specific organisms can use "electrical polyspermy blocks" (the fast process), which changes the negative electrical charge of the egg to positive, thus repelling the also positively charged sperm. The slower prevention process is when an organism undergoes a secretion reaction, or a cortisol reaction, which contributes to envelopping the egg by changing its membrane.
