What is the genetic combination for males?
In humans, a male offspring is normally produced when the child inherits an X chromosome from Mom, and a Y from Dad. The male is said to be XY, the female XX.This is a common method of sex determination in animals. However, there are various other ways in which the sex is decided. Here are some examples: * In birds, butterflies, and moths, it is the male that has two similar chromosomes (WW) and the female that has two different sex chromosomes (WZ). * In honey bees, males are haploid. If the ovum is fertilized, the embryo develops into a female. * In some marine worms, the sex of the larva is not determined until it settles on a substrate. In Bonellia viridis, for example, if the larva settles on the sea bed it becomes a female, but if it settles on a female it develops into a male. * Some fish change sex as they mature. Burramundi is an example: the young fish is male, then turns into a female.
