It's the male gamete that decides the intercourse from the offspring.
Ronald Fisher proposed that intercourse could aid the unfold of beneficial genes by permitting them to better escape their genetic surroundings, if they need to come up on the chromosome with deleterious genes.

It implies this equipment advanced in two unique bouts divided by an extended period of stasis; very first the appearance of recombination machinery inside a bacterial ancestor which was taken care of for 3 Gy(billion years), till the neomuran revolution when the mechanics were tailored towards the presence of nucleosomes. The archaeal items on the revolution taken care of recombination machinery which was primarily bacterial, While the eukaryotic solutions broke using this bacterial continuity. They launched cell fusion and ploidy cycles into mobile everyday living histories.
