The two sexes exist for sexual reproduction. That is, to enable optimum genetic transfer for the species through survival of … Yes, there are organisms and stuff that are asexual and can reproduce solely on their own. Populations of most isogamous protists have gametes that belong to one of only two mating-types (alias sexes). And four sexes for the population, Parker argues. has to do with their biological function. That’s because there are two strains of queens in this ant population, which is probably a hybrid of two different species that became genetically interdependent. These are conceptions of life, personalities, disorders, and afflictions. Asexual reproduction can efficiently produce twice as many offspring as sexual reproduction without the complications of finding and courting a mate. There are, we just didn't evolve from those organisms. There is a type of flatworm that reproduces sexually, but is hermaphroditc. That this should be so is paradoxical for, if there is any cost involved in the finding of a mate, then a gamete of a third mating-type would, at the point of invasion, be able to mate with the first gamete it encounters, hence suffering the minimum possible costs. In meiosis, which is more complicated than it used to be, the two strands of genes that form the double helix in the nucleus of a cell separate into two haploid cells, which eventually are ready to recombine with a haploid cell from a sexual partner to begin the life of a new human being. It reminds me of "Slaughterhouse-Five" which has a part where the guy goes to a planet where there are more than two sexes. Makes no fucking sense to me. God created us in his image.

The OP’s question as to why there are two genders is different from, though related to, the question as to why there is sexual reproduction. Five weeks into development, a human embryo has the potential to form both male and female anatomy. As strange as it might seem, answering this biology question with a formal proof makes good sense. It seems two sexes is far more conducive to success in multi-cellular organisms than three or more.

I don’t think anyone knows for sure why we have two genders. Think of all the time wasted on trying to hook up. Are there only two sexes?
