Learn about the biological systems that determine sexual characteristics in organisms, such as the XX/XY system found in humans and most mammals. Compare different chromosomal systems, environmental systems, and evolutionary aspects of sex determination.
4 dni temu · Learn how the X and Y chromosomes determine biological sex in humans and other mammals. Find out how sex-linked traits, sex-chromosome disorders, and hormone abnormalities affect sex development.
Learn how sex chromosomes determine biological sex and what genes they carry. Find out how XY chromosomes make males and what conditions are linked to them.
In most mammals, females are XX, and can pass along either of their Xs; since males are XY they can pass along either an X or a Y. Females in such species receive an X chromosome from each parent while males receive an X chromosome from their mother and a Y chromosome from their father.
