Human Sex Determination

Describe the chromosomal basis of sex determination in humans.

Identify that one of the 23 pairs of human chromosomes is responsible for determining the biological sex of the individual.

Recall that human females possess two identical sex chromosomes (XX), while human males possess two different sex chromosomes (XY).

Understand that all female egg cells contain an X chromosome, whereas male sperm cells can carry either an X or a Y chromosome.
