Why human male is Heterogametic and female is Homogametic?
Sex Differences in Longevity and Aging The heterogametic sex is the one in which the sex chromosomes differ. For instance, in mammals males are the heterogametic sex as they have one X and one Y chromosome, whereas females are the homogametic sex, because they have two X’s.Click to see full answer.

Similarly one may ask, why are men said to be Heterogametic sexes?Males typically have two different kinds of sex chromosomes (XY), and are called the heterogametic sex. In humans, the presence of the Y chromosome is responsible for triggering male development; in the absence of the Y chromosome, the fetus will undergo female development.Likewise, are females Homogametic? For example, in humans (and most other mammals), the female is the homogametic sex – females have two identical homologous chromosomes (XX), whereas males, the heterogametic sex, have two homologous chromosomes of different sizes with different genes (XY). Also know, what is male Heterogamety? Heterogamety means different sex gametes. Male heterogamety includes human males having XY sex chromosomes and males of some insects, such as grasshopper and bugs, having XO sex chromosomes.What is the gender of YY?Instead of having one X and one Y sex chromosome, those with XYY syndrome have one X and two Y chromosomes. Sex chromosome abnormalities like XYY syndrome are some of the most common chromosome abnormalities. XYY syndrome (also called Jacob’s syndrome, XYY karyotype, or YY syndrome) affects only males.
