Secondary intercourse characteristics are determined by the hormones the gonads secrete. These characteristics consist of your body’s phenotype (how it looks) outside with the reproductive system.
A chromosome is a DNA molecule that contains genetic content. Sex chromosomes are chromosomes that affect your sexual anatomy and reproductive development.

The stable, heterogametic sexual intercourse chromosomes in some lineages, notably mammals and birds, were recently thought to become the result of an evolutionary trap; the intercourse-confined Y or W contains many genes with sex-specific effects, the loss of which would be detrimental towards the heterogametic intercourse (Bull and Charnov 1977; Bull 1983; Pokorná and Kratochvíl 2009). However, recent work has shown that even inside the XY system of mammals, thought to get among the list of most stable, genes can shift from the Y chromosome on the autosomes (Hughes et al.

However, further more work in Paleognath birds, like the emu, exposed that not all aged intercourse chromosome systems will have a degenerated heteromorphic sexual intercourse chromosome (W or Y). In contrast to birds, mammals and flies, the plants studied to date have much younger sexual intercourse chromosomes, which facilitate the analyze of how quickly recombination suppression evolves between the intercourse chromosomes. The 10–20 million year aged X and Y chromosomes of Silene latifolia have already experienced three recombination-suppression events, but there are compact areas within the distal arm of such intercourse chromosomes that can still recombine. The evolutionary rate at which speedy recombination suppression occurs could, however, be highly variable. The seven-million-year-aged papaya intercourse chromosomes are largely in a position to recombine, with rather tiny sexual intercourse-certain locations. Curiously, in both papaya and S. latifolia, the Y-certain areas are larger than the X-specific regions. It really is only by studying diverse taxa that we are able to acquire truly general expectations for intercourse chromosome evolution
