D. Genetic Engineering
Doesn’t matter if it takes hundreds of years or a couple weeks, if there is an intent to alter the genes of an organism to select for desired traits, it is genetic engineering.

In human, Oogenesis in comparison to spermatogenesis is different in that Oogenesis does not complete meiosis until after fertilization, but spermatogenesis is complete before the sperm leave the body. Oogenesis is the process by which the female gametes, or ova are created in the female's ovary. Spermatogenesis is the process in which males synthesis sperms. The two process are part of gametogenesis which involves meiosis type of cell division, in which a diploid cell divides into four haploid daughter cells.
