Sex determination in the unborn baby?

Sex determination in an unborn baby is determined by the combination of sex chromosomes inherited from the parents. Typically, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). During fertilization, the father's sperm can contribute either an X or a Y chromosome, determining the genetic sex of the offspring. This process occurs at the moment of conception and is responsible for the development of the baby's sex characteristics.


How does the temperature of male scrotal determine the sex of a baby?

The temperature of the male scrotum does not determine the sex of a baby. The sex of a baby is determined by the chromosomes present in the sperm, with an X chromosome resulting in a female baby and a Y chromosome resulting in a male baby. The temperature of the scrotum can affect sperm production and quality, but it does not influence the baby's sex.

Who makes the sex of a baby?

The sex of your baby is tottally dependant upon the male's sperm, each sperm has a specific sex chromosome, either a Y or an X . every egg of a female has only X sex chromosomes. When one sperm conjoins with one egg, the female gives her X chromosome and the male gives the chromosome (either X or Y) belonging to the sperm that made it to the egg first and will determine the sex. XX = Female XY = Male * All the things you hear about eating meat during your pregnancy will produce a boy and fruits will produce a girl are myth!

Which sex cell controls the sex of a baby?

I will explain, but I don't know why you put this in cat behavior. The X chromosome and Y chromosome control gender. If an embryo's two chromosomes are XX, it will be a girl. If the chromosomes are XY, it will be male. A pair of chromosomes have to have at least one X chromosome in it, but can also have a Y chromosome.
