@DarrenSnider "Most animals are diploid organisms, meaning that their body (somatic) cells are diploid and haploid reproductive (gamete) cells are produced through meiosis. Some exceptions exist: for example, in bees, wasps, and ants, the male is haploid because it develops from unfertilized eggs."
-Section 27.1, Biology 2e, by Mary Ann Clark, Matthew Douglas, Jung Choi
That both a male and a female gamete contribute to the zygote is vitally necessary -- debilitating human diseases result from disturbing the imprinting of even single genes (Prader-Willi syndrome, Angelman syndrome, etc.). Yet 100 or more genes are imprinted in total. Disrupting imprinting for all of them is incompatible with life. This explains why the male-female binary at the organismal level is so tightly locked in place in mammals.
-Georgi K. Marinov, Postdoctoral Research Scholar at the Department of Genetics, Stanford University School of Medicine
