Does the male or female determine the gender of a baby? how?

Answer 1

The dad does. Cause we got the Y chromosome.
What determines the sex of my baby?



Your baby's identity as male or female is determined at fertilization by the type of male sperm that fertilizes the egg.



Males have two types of sperm:

y-chromosome sperm (male)

x-chromosome sperm (female)



If a y-chromosome sperm fertilizes the egg, you are carrying a girl. If an x-chromosome sperm fertilizes the egg, you are carrying a boy

Answer 2

The male gamete(sex cell) determines the gender of the offspring or baby BECAUSE, the male contains the X and Y chromosomes. On the other hand, the female gamete has two(2) X chromosomes and no Y. During fertilization, the chromosomes assort themselves to combine as XX or XY.

A baby is a boy(male gender) if the chromosomes are X and Y. A baby is a girl if it has both X chromosomes.
Since the male gamete is the only one contributing the Y chromosome so, it is generally accepted that the male determines the gender of the baby.

However, if you want to be "philosophical" about it, hey, you can say the female gamete will determine the the sex of a female baby since there are just X's. It is important to note however that one of the other X's came from the male gamete. So there, it is the male that determines the gender of the baby.

Answer 3

Hmm. All the answerers are assuming that you are a human. I am going to assume that you are a bird and give you a different answer.

In humans XY is male and XX is female. These chromosomes carry most of the genes that determine our phenotypic sex. The XY combination is called "heterozygous" meaning different genes, and the XX combination is called "homozygous" meaning the same genes.

Birds are different in that their male and female sex-chromosome roles are reversed from mammals, meaning that the female is heterozygous and the male is homozygous. Also, in birds we use Z and W instead of X and Y. (These letters refer to the general shapes of the chromosomes.) So, a male bird is ZZ, and a female bird is ZW. So in birds, the chromosome from the female determines gender.

Back to pretending you are a human. The answer that the sperm determines the gender is correct, however the female can certainly influence this a lot. Do a search for "gender selection".

Answer 4

The male does, as the female only produces eggs with an X chromosome. The male sperm can contain either an X or a Y chromosome. if the male X sperm fertilizes the female egg the result is an XX which is female. However, if the male Y sperm does the fertilization then the resultant offspring will be an XY which is the male.

Answer 5

The female gets no choice in the matter, as she has only X chromosomes. The male has both X and Y. Two X's make the baby a girl, while X and Y together make it a male.

Answer 6

The gender is determined by the sperm, sperm, which is the male cell carries inside 2 genomes, x or y, the ovules, the female cell is y, when the 2 cells blend together the male cell gives it genome to make the combination xx for the men and xy for the women.

Answer 7

dad because the dad has the XY chromosome and the mom has the XX so XY is boy AND XX is girl a person can not survive with 2 y chromosomes

Answer 8

Dad, because he's the one with the Y chromosome. Moms only carry Xs.
