Though those two chromosomes set with one another during meiosis, there was frequently extremely homology that is minimal recombination among them, primarily as a result of a sizable huge difference in their hereditary content and size. Usually one chromosome is smaller, and seems to retain just those genes which can be needed for intercourse dedication.
In evolutionary timescales, the look of distinctly various intercourse chromosomes, or heteromorphic intercourse chromosomes, is a comparatively current occasion. The very first cases of intimate dimorphism, where male and female reproductive organs have been in various people, are believed to own arisen through temperature-dependent intercourse dedication, where some genes are switched on or off with regards to the temperature that is ambient.
