Learn about the xx and xy chromosomes, the sex determination system, and other chromosome combinations. In this system, the sex of an individual usually is determined by a pair of sex chromosomes Typically, females have two of the same kind of sex chromosome (xx), and are called the homogametic sex. The extraordinary complexity of sex determination a host of factors figure into whether someone is female, male or somewhere in between You probably remember this legendary illustration in a biological textbook Sex chromosome (chromosome) is a microscope, female is xx and male is xy.
The thing is, xx and xy chromosomes aren’t cut and dry, either 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. Females receive two x chromosomes, represented by xx Males receive an x and a y chromosome, represented as xy But where do the x and the y come from
To understand how this happens, let’s look at a special type of cell division called. Sex chromosomes are more complex than most people think While we’re usually taught that there are two types — xx and xy — many more variations exist.
