How does the father determine the gender of a child?

The father determines the gender of a child through the contribution of his sperm during fertilization. Sperm carries either an X or Y chromosome, which combines with the mother's X chromosome to determine the baby's gender. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.


Who determines the sex of the baby in humans?

The father determines the sex of the baby in humans. Sperm cells contain either an X or Y chromosome, and the sperm that fertilizes the egg will determine the sex of the baby. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.


How do testosterone levels impact the gender of a baby?

Testosterone levels do not directly impact the gender of a baby. The gender of a baby is determined by the chromosomes inherited from the parents. Specifically, the presence of a Y chromosome from the father will result in a male baby, while the absence of a Y chromosome will result in a female baby. Testosterone levels may influence the development of male characteristics in a baby after conception, but they do not determine the baby's gender.


If your husband has a lot brothers will you birth a lot of sons?

No. The gender of the baby is always a 50/50 chance. Females have two X chromosomes, while males have one X and one Y. If the father gives the X chromosome, then the baby will be a girl (XX) but if the father gives a Y chromosome then the baby is a boy (XY). Whether he gives an X or a Y is completely random.


Whose chromosomes determine the sex of offspring in humans?

The males chromosomes determine the gender of the baby. Women have an XX chromosome and men have an XY chromosome. So women can only give an X chromosome, but men can give either/or.The chromosomes of the father make the final determination; the child either gets a X from the mother and either an X from the father which makes a girl, or an X from the mother and a Y from the father, which makes a boy.Jamiana:The Father's(it's Y though)

Does men or women determine the sex of a baby?

The sex of a baby is determined by the sperm from the father. Males have both X and Y chromosomes, while females have two X chromosomes. When a sperm carrying an X chromosome fertilizes an egg, the resulting baby is female (XX); if a sperm carrying a Y chromosome fertilizes the egg, the baby is male (XY). Thus, it is the father's sperm that ultimately determines the sex of the baby.


How do genetics make a baby?

In general, the mother contributes an (X) chromosome and the father can contribute either and (X) OR (Y). Therefore, X/X = GIRL and X/Y = BOY. So, the father is ultimately controlling the gender of a baby.


What determines the breed of a baby chick?

The breed of a baby chick is determined by the genetics passed down from its parents.
