Technically, the father determines the sex of the offspring. There are two sex chromosomes: the "X" and the "Y". If an embryo has "XX", it will develop into a female, while the "XY" combination results in a male offspring.

To understand why, a little knowledge of Miosis is needed (this is the process by which sex cells are created (eggs and sperm)). Miosis is related to Mitosis, in that the end result is the creation of two cells from one. Miosis, however, ensures that half the genetic material is handed to each "daughter" cell, while Mitosis results in equal and even distribution (cock) of genetic material.
If all men are "XY" (they are), then the process is pretty straightforward: Each of the sperm must have half the normal genetic material. This means that each must have either an "X" or a "Y" chromosome. If you're a dude, 50% of the sperm will result in male offspring, and 50% will result in female. Females have two "X" chromosomes, so even when only half is replicated, there's a 100% chance an "X" is present. Everyone needs two sex chromosomes to grow, so, therefore, if 100% of the time the mom is giving an "X", and half the time the pop is shooting "X"'s and "Y"'s, it's fully the dad's genes that decide of the offspring is male or female.

Who determine the sex of the baby?

A baby's sex is determined by two chromosomes the "x" and the "y" females are naturally "xx" and a male is "xy" the males sperm is made up of many "x" and "y" chromosomes thus making the male responsible for the sex of the child

How do you determine the sex of a baby chicken?

Sexing chicks is a very difficult job to do well. Vent sexing or identifying the sex of a day old chick by looking at its sexual organs is done by very few, very well trained people. It takes a long time to learn how to identify the more than 15 different shapes. Feather sexing is based on feather characteristics that differ between male and female chicks.The feather appearances are determined by specially selected genetic traits that must be present in the chick strain. Most breeds of chickens do not have these feather sexing characteristics and the feathering of both sexes appear identical. The easiest method of sexing chickens by the small flock owner is to care for the birds until they begin showing the natural secondary characteristics of their sex. In males, the combs and wattles will become larger than those on females and the head will become more angular and masculine looking. The female will remain smaller than the male and is more refined or feminine looking. Sexing based on secondary sex characteristics can usually be done after chicks are 4 to 6 weeks of age.

What is the gene that determines the sex of an offspring?

With people, girls have XX and guys have XY chromosomes. ---------------------------------------------------------------------- This mechanism of how this genetic sex determination works varies:- With many animals, females have two of the same kind of sex chromosome (XX), while males have two distinct sex chromosomes (XY). Some species (including humans) have a gene SRY on the Y chromosome that determines maleness; others (such as the fruit fly) use the presence of two X chromosomes to determine femaleness. There are variants to this mechanism to be found in insects which use an XX/X0 mechanism:- In this variant of the XY system, females have two copies of the sex chromosome (XX) but males have only one (X0). The 0 denotes the absence of a second sex chromosome. Another variation found in birds uses the ZW chromosome set:- The ZW sex-determination system is reversed compared to the XY system: females have two different kinds of chromosomes (ZW), and males have two of the same kind of chromosomes (ZZ) One must also consider the way animals such as bees determine sex, this is called Haplodiploidy:- In this mechanism, unfertilized eggs develop into haploid individuals, which are the males. Diploid individuals are generally female but may be sterile males. Thus, if a queen bee mates with one drone, her daughters share ¾ of their genes with each other, not ½ as in the XY and ZW systems. With other animals genes play no part in the determination of sex, for instance in some species of reptiles, including alligators, some turtles, and the tuatara, sex is determined by the temperature at which the egg is incubated While other species, such as some snails, practice sex change: adults start out male, then become female. In many tropical reef fish, the dominant individual in a group becomes female while the other ones remain male, Also in some species individuals have no real sex differentiation at all, for instance Earthworms are hermaphrodites.

What is my father's mother's sister's brother's mother's fathers' sister's baby called?

your father is your father and your fathers mother is your grandmother and her sister is your great aunt and your grandmas brother is your great uncle and since their brother and sisters their mom is your great grandma your great grandmas father is your great great grandpa and his sister is your great great great aunt and her baby would probably (i think) be either your 3rd cousin

Does the female determine the sex of the baby?

No. The male determines the sex. A female has 2 X chromosomes, while a man has an X and a Y. A woman can only give an X, but a man can give an X or a Y, thus making the sperm cells the determining factor.

How can a child get father's genes if he is born through mother's womb?

A child starts out as a one-celled organism called a zygote, which is formed when the father's sperm, containing half the father's genes, fertilizes the mother's egg, which contains half the mother's genes. So the process of fertilization, which occurs in the mother's fallopian tube, combines half of the father's genes and half of the mother's genes. After fertilization, the zygote divides into an embryo and makes its way to the mother's uterus (womb) where it is implanted and continues to grow and develop.

Is it the father's gene that decides whether the baby is a boy or a girl?

Yes it is from the father that this comes but not at the level of asingle gene. The genes that determine sex are to be found on thesex chromosomes, of which every person has two. They come in twotypes X and Y. Woman have an XX pair and Men have an XY pair. Thusas you can see the Y chromosome is that which makes the differenceand this comes from the man.
