The answer is a sexual reproduction. This is due to the formation of gametes that enable the variation of the offspring of the parents. Firstly, each gamete contributes half the genetic material (alleles)from either parent. The dominant alleles will show in the phenotype of the c=ofspirng. Additionally, during meiosis (the process that makes gametes), recombination of genetic material can occur hence transferring unique combination of genes from that of the parent. Therefore, there are many possible combinations of gametes that gives the offspring variance from the parents
