Can a female have Y chromosome?

Each person normally has one pair of sex chromosomes in each cell. The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes.

Can an XY female get pregnant?

Males and most XY females cannot become pregnant because they don’t have a uterus. The uterus is where the fetus develops, and pregnancy isn’t possible without it. In most cases, having a Y chromosome means having no uterus, so pregnancy isn’t possible.

What chromosome is female?

Here, females carry two X chromosomes (XX) and only produce gametes with X chromosomes. Males, on the other hand, carry only one X chromosome (XO) and produce some gametes with X chromosomes and some gametes with no sex chromosomes at all (Figure 5). Figure 6: Sex determination in birds.

Can a human be YY?

Males with XYY syndrome have 47 chromosomes because of the extra Y chromosome. This condition is also sometimes called Jacob’s syndrome, XYY karyotype, or YY syndrome. According to the National Institutes of Health, XYY syndrome occurs in 1 out of every 1,000 boys.
