In this way, what are the genes on the Y chromosome responsible for?
Because only males have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and development. Sex is determined by the SRY gene, which is responsible for the development of a fetus into a male.
Similarly, what traits are passed on the Y chromosome? The Y chromosome is a puny bit of DNA that has only a few genes. And the genes it does have mostly deal with being male. So the only traits that are passed from father to son through the Y are those that turn an embryo into a male and those that make a man fertile once he reaches puberty.
Beside above, what is the gender of YY?
Instead of having one X and one Y sex chromosome, those with XYY syndrome have one X and two Y chromosomes. Sex chromosome abnormalities like XYY syndrome are some of the most common chromosome abnormalities. XYY syndrome (also called Jacob's syndrome, XYY karyotype, or YY syndrome) affects only males.
Where is the Y chromosome located?
STRUCTURE OF THE Y CHROMOSOME Genes in the two pseudoautosomal regions (PAR1 and PAR2) as well as those in the nonrecombining Y region (NRY) are illustrated. The Pseudoautosomal regions (PAR): PAR1 is located at the terminal region of the short arm (Yp), and the PAR2 at the tip of the long arm (Yq).
