Answer 1

the Y chromosome in zygote

Explanation -

In humans, the sex of the child is determined by the sex chromosome inherited in the zygote from the father. A human male has X and Y sex chromosomes. If a zygote receives X chromosome from the father, it will develop into a female and if a zygote receives Y chromosome from the father, it will develop into a male.
