OpenStudy (anonymous):

to distinguish whether a person is male or female, there are two types of chromosomes that highlight this;an X chromosome and Y chromosome. In order for a person to be a male, you need to have one X and one Y chromosome. To be female, you need two X chromosomes.

What about the species hah? ovarium and testis may be xD

OpenStudy (dean.shyy):

For humans, males have a reproductive organ that consist of two testicles, which lie in a scrotal sac, and a penis. On the other hand, females have an orifice opening known as the vagina, and leads into the vaginal canal. The distinction is very clear if both genders are naked. However, there are times when clothing may create an illusion. Therefore, to determine gender differences, many factors can be considered. For males, you are able to notice short hair, a muscular body, and a deep voice. On the other hand, females have long hair, a lighter voice, and a less muscular body. If no distinction can be made, the last resort would be to ask the individual if they are female or male.
