But if the egg gets a y chromosome, the baby is xy, or male. The xx/xy system is found in most other mammals, as well as some insects In this system, females have two of the same kind of sex chromosome (xx), while males have two distinct sex chromosomes (xy). Actually, sex chromosomes and genetic expression vary widely, beyond a penis/vagina or xy/xx binary Xx and xy with the aforementioned expressions are the most common sex chromosomes and corresponding organs, but they’re not the only ones. The extraordinary complexity of sex determination a host of factors figure into whether someone is female, male or somewhere in between
Individuals having two x chromosomes (xx) are female Individuals having one x chromosome and one y chromosome (xy) are male The x chromosome resembles a large autosomal chromosome with a long and a short arm. If the sperm that fertilises the egg carries an x, the baby will have two x chromosomes (xx), typically developing as female If the sperm carries a y, the baby will have one x and one y chromosome (xy), typically developing as male.
