In humans, the male determines the sex of the fetus. The mother has 2 X chromosomes and each egg she produces just has an X. Males have both X and Y so they can have a sperm with X and a sperm with Y. A female fetus has XX, one from mom and one from dad. A male fetus has one X from mom and a Y from dad.
to see if he has more of his father genetics
They determine the sex of the offspring in Humans.
How confident the male is that the offspring produced by the female is his
In humans, it is the father's chromosomes that determine the sex of offspring. The father contributes either an X or a Y chromosome, while the mother always contributes an X chromosome. If the combination is XX, the offspring is female, and if it's XY, the offspring is male.
The sex chromosomes determine the sex of an organism. In humans, it is the 23 pair. Females pass on either or their X chromosomes, while males pass on either their X or their Y. If the male passes on their X chromosome, the resulting offspring is female. If they pass on their Y chromosome, the resulting offspring is male.
the father does. you see a woman genes are both y and men's genes have an x and a y if the father gives a y it is going to be a girl if he gives it and x it will be a boy. that is what determines sex of an offspring also if you already have some kids that will give you a better guess of what sex the offspring is.
The male
No it doesn't
because the male can either give an X or a Y
Chromosomes. XX=female XY=male
They determine the sex of the offspring in Humans.
The male offspring of a person is called that person's Son.
Just because the male determines sex of the offspring, doesn't mean that in all species of animals do males dominate.
They are the offspring of female horses and male donkeys.
An offspring will only be male if it has a Y chromosome.
X and Y chromosoms determine whether or not an offspring is a male or female. Chromosomes come in pairs. Boys have an X and a Y chromosome pair; girls have an X and an X chromosome pair.
"Proven" refers to whether or not a male alpaca has sired offspring that carry his desireable genetic traits. An unproven alpaca, therefore, is a male that has either not been bred or does not have enough offspring old enough to determine if he will pass on the desired traits. A proven alpaca is a male that has sired offspring that carry his desired traits, which makes him more valuable as a breeding animal.
Men do they are the carriers of the X and Y chromosome. Girls only have X chromosomes. Two X chromosomes mean it will be a girl and a X and a Y mean it will be a boy.
