Xx Chromosome Gender Members-Only Content Refresh #719

There are two kinds of sex chromosomes Sex chromosomes decide whether you’re biologically male (xy) or female (xx), but they don’t define your gender. Xx chromosomes = vagina & ovaries = woman Gender is subjective to each person, and sex organs don’t dictate gender People with penises aren’t necessarily men, and people with vaginas aren’t necessarily women The thing is, xx and xy chromosomes aren’t cut and dry, either. 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. These consist of two x chromosomes in females, and an x chromosome and a y chromosome in males Females therefore have 23 homologous chromosome pairs, while males have 22 The x and y chromosomes have small regions of homology called pseudoautosomal regions. People usually have two sex chromosomes Typically, embryos with one x and one y chromosome develop into males And those with two x chromosomes usually become females We get one sex chromosome from our fathers, carried by sperm, and one from our mothers, carried by the egg. We’re usually told that people with xy chromosomes are male and people with xx chromosomes are female It’s a lot more complicated than that Typically, there are 46 chromosomes in each human. Sex chromosomes are the pair of chromosomes that help determine a person’s biological sex Typically, people have either xx chromosomes (usually associated with female development) or xy chromosomes (usually associated with male development). Females usually have two x chromosomes (xx), while males have one x and one y chromosome (xy) You probably remember this legendary illustration in a biological textbook Sex chromosome (chromosome) is a microscope, female is xx and male is xy.
