What is the role fertilization in natural selection
- During fertilization, genes from different parents are mixed independently in different combinations. This introduces variation in the genetic constitution of the offspring.
- As a result of variation organisms become efficiently adapted to survive in different environmental conditions.
- A selection pressure acts on these variations; organisms with more favorable variations survive and reproduce while those with unfavorable variations die and maybe weeded out. This may lead to emergency of new strains of organisms with favorable variations.
