Answer:
Sexual reproduction increases the genetic variation of a species because it involves combining of genetic materials of two parents/individuals to form an offspring.
Explanation:
Sexual reproduction is a type of reproduction that involves formation of an offspring by combination of male and female gametes. Each gamete carries a haploid set of chromosomes. When gametes from both the parents combine, a zygote is formed which has a diploid set of chromosomes. So, sexual reproduction involves combination of genetic materials of two different individuals, hence, it leads to genetic variation.

Mutation of proto-oncogene leads to cancer, but tumor suppressor gene prevents it.
Cancer will be spread out because of tumor suppressor gene (P53) mutation.
the place of P53 is 17th gene(to be specific 17p13.1).
