Question

In humans, a combination of XX chromosomes results in a female zygote and that of XY results in a male zygote. From whom does a male zygote inherit an X chromosome

Answer 1

The male zygote gets the X chromosome from the female.

Answer 2

The male zygote receives the X chromosome from its mother.

Step-by-step explanation:

The sex chromosomes are represented by the letters X and Y. A karyotype formed by the chromosomes XX indicates female sex, while the one with XY indicates male sex.

All gametes (eggs) formed by meiosis in a woman have the X chromosome, while men can form gametes (sperm) that have the X chromosome and others that have the Y chromosome. That is why we say that women are the homogametic sex and men are the heterogametic sex. In this case, we can confirm that male individuals who have the XY chromosome, received the X chromosome from their mothers.
