Question

Describe the chromosomes needed for an embryo to become a female and those needed for an embryo to become a male.

Answer 1

An embryo needs to have two XX chromosomes in order to be a girl and the XY chromosomes to be a boy.

Step-by-step explanation:

Female eggs only have the X (female) chromosomes, while the male sperm cells have both the X and Y (male) chromosomes. If the X from the male and X from the female unite, then the child will be female. If the Y from the male and X from the female unite, then the child will be male.

Answer 2

The chromosomes needed for an embryo to become a female is the X chromosomes from a female egg and X chromosome from the male sperm cells though, males have both X and Y chromosomes.

In addition, the chromosomes needed to have an embryo to become male is the X chromosome from the female and the Y chromosome from the male.

Therefore, if the X and Y chromosomes unite, then the child will be male and if X and X chromosome will bind, a female child will be born.
