Question 19

asexual reproduction vs sexual reproduction

AR
energy and time conserving process
Through asexual reproduction, organisms in isolation can incite their population
when the environmental conditions are favorable
the population have the same genetic makeup as the parents

SR
yield a small number of offspring and the entire reproductive process takes a longer period of time
mixing of the gene pool of the species, causing a better chance of surviving
the sexual process is that it reduces the effects on the environment
we cannot control what our offspring looks like
