What’s an intercourse linked trait – The intercourse chromosomes are one set

The sex of the individual is determined by sex chromosomes in humans, as well as in many other animals and some plants. The intercourse chromosomes are one couple of non-homologous chromosomes. Up to now, we now have only considered inheritance habits among non-sex chromosomes, or autosomes. As well as 22 homologous pairs of autosomes, peoples females have homologous set of X chromosomes, whereas individual men have actually an XY chromosome set. The Y chromosome is much shorter and contains many fewer genes although the Y chromosome contains a small region of similarity to the X chromosome so that they can pair during meiosis. Each time a gene being examined occurs on the X chromosome, yet not on the Y chromosome, it is known to be X-linked.

Figure 1. In Drosophila, the gene for attention color is situated in the X chromosome. Clockwise from top left are brown, cinnabar, sepia, vermilion, white, and red. Red attention color is wild-type and it is principal to eye color that is white.
