Trait that determines an organism's sexually reproductive function
Sex is the biological trait that determines whether a sexually reproducing organism produces male or female gametes. During sexual reproduction, a male and a female gamete fuse to form a zygote, which develops into an offspring that inherits traits from each parent. By convention, organisms that produce smaller, more mobile gametes (spermatozoa, sperm) are called male, while organisms that produce larger, non-mobile gametes (ova, often called egg cells) are called female. An organism that produces both types of gamete is hermaphrodite. .
