Sexual reproduction evolved multiple times in various groups of organisms. sexualmost always involved meiosis followed by gamete release and fertilization. what explains why the phenomenon of sexual reproduction was under selective pressure to evolve multiple times in groups of organisms?
a)
sexual reproduction produces more offspring in one event than asexual reproduction. greater numbers of offspring is a survival advantage.

b)
sexual reproduction requires less energy expenditure on the part of the organisms and thus provides a better allocation of resources for the sexually reproducing individual.

c)
sexual reproduction produces genetically diverse offspring. genetically diverse populations are more resilient to environmental disturbance and are less likely to go extinct.

d)
sexual reproduction limits the genetic variation in a population, providing for a mechanism to create genetically stable offspring. these offspring are more likely to survive.
