Step-by-step explanation:
An individual who has an abnormal chromosomal makeup and mixed or indeterminate male and female sex characteristics is called intersex. Intersex is a general term used to describe people whose sex traits, reproductive anatomy, hormones, or chromosomes are different from the usual two ways human bodies develop. Some intersex traits are recognized at birth, while others are not recognizable until puberty or later in life. There are many causal factors that can make a person intersex, such as having a different number of sex chromosomes or hormonal activity during development.
