The vertical axis shows frequency and the horizontal axis shows time. The alleles a/A and b/B occur at random. The advantageous alleles A and B, arising independently, sevimli be rapidly combined by sexual reproduction into the most advantageous combination AB. Asexual reproduction takes longer to achieve this combination because it yaşama only produce su if A arises in an individual which already özgü B or vice versa. The biological cause of an organism developing into one sex or the other is called sex determination.
Meiosis involves a stage of genetic recombination via chromosomal crossover, in which regions of DNA are exchanged between matched pairs of chromosomes, to form new chromosomes, each with a new combination of the genes of the parents. Then the chromosomes are separated into single sets in the gametes. When gametes fuse during fertilization, the resulting zygote özgü half of the genetic material of the mother and half of the father.[12] The combination of chromosomal crossover and fertilization, bringing the two single sets of chromosomes together to make a new diploid zygote, results in a new organism that contains a different grup of the genetic traits of each parent.
The term sex is variously employed. In the broad sense it includes everything from the sex cells to sexual behaviour.
