Sexual reproduction evolved multiple times in various groups of organisms. Sexual reproduction differs across the various groups
, but almost 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?
C. Sexual reproduction produces genetically diverse offspring. Genetically diverse populations are more resilient to environmental disturbance and are less likely to go extinct.
Explanation:
Genetic diversity is the greatest advantage of sexual reproduction. Other than random mutations, asexual reproduction offers no genetic diversity. A population of clones that lack genetic diversity are at a much greater risk for population decline and extinction in a changing environment.
