How to Determine Heterogametic?

The male phenotype is determined by presence of a single X chromosome and two copies of each autosome. In mammals, females are the homogametic sex, and males are the heterogametic sex. In most birds, reptiles, and amphibians, the female is the heterogametic sex.

How could you determine if your karyotype is male or female?

Females have two X chromosomes, while males have one X and one Y chromosome. A picture of all 46 chromosomes in their pairs is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.

Which is the Heterogametic female?

Heterogametic sex (digametic sex) refers to the sex of a species in which the sex chromosomes are not the same. For example, in humans, males, with an X and a Y sex chromosome, would be referred to as the heterogametic sex, and females having two X sex chromosomes would be referred to as the homogametic sex.
