Meiosis and fertilization are important processes because they may most immediately result in (1) many body cells (3) immune responses (2) genetic variation (4) natural selection

(2) genetic variation

Explanation:

Meiosis is the process whereby sexually reproducing organisms produce haploid (n) gametes or sex cells via division while fertilization is the fusion of the gametes (male and female) produced as a result of meiosis to form a diploid (2n) zygote.

Meiosis is a phenomenon that is unique to only sexual reproduction and it aims at producing daughter cells that are genetically different from the parent cell. A process called CROSSING OVER, which occurs only in meiosis, enables offsprings that results from the fertilization of the gametes produced by meiosis to exhibit GENETIC VARIATION i.e. difference in genetic content from parent cell.

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents
