canada goose coats Dr Mary McMillan is a lecturer at the School of Science and Technology, University of New EnglandMay 7 2019 7:00AMSex is more complicated than just X and YDr Mary McMillanWhether we develop male or female characteristics mostly comes down to the presence, or absence, of a gene on the Y chromosome, called the sex determining region Y (SRY) gene.Early in embryonic development, the protein produced from this gene initiates the development of testes, and prevents the development of ovaries. In the absence of this protein, female structures will develop.This is why most people who have two X chromosomes develop as females, and most who have an X and a Y develop as males.But what happens if the SRY gene is present on the Y chromosome, but the gene is non functional? Or if there is a Y chromosome that is missing this SRY gene?In these cases an embryo, despite having a Y chromosome, will develop female characteristics.So yes, there are females who have an X and a Y chromosome.This then raises the question, can the opposite happen? Can someone with two X chromosomes ever be male? The answer, again, is yes.Some people inherit an abnormal X chromosome, which has a copy of the SRY gene. If this happens, they will develop male characteristics, despite lacking a Y chromosome. canada goose coats
