Q

What type of cell division is responsible for the production of our gametes or sex cells?

A

MEIOSIS

18
Q

22
Q

is a condition in which individuals with XY chromosomes have a genetic mutation that makes their bodies insensitive to androgens (male sex hormones). As a result, they may develop external female genitalia and often identify as females, despite having XY chromosomes.

A

ANDROGEN INSENSITIVITY SYNDROME

23
Q

are a pair of chromosomes that determine an individual’s biological sex. In humans, there are two types of sex chromosomes: X and Y. Females typically have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
