This has to do with basic genetics. Women always pass on an X chromosome to a baby, and men can pass on either an X or a Y. A girl has two X chromosomes one from mom one from dad. A boy has one X and one Y. X from mom Y from dad, so the father decides gender based on what he passes on to the child.
The female carries two chromosomes both of them X
The male carries two also but they are X and Y
When the sperm impregnates the egg, if it is a Y it is a boy
if the sperm impregantes it with an X, then it is a girl.
The reason is that the SRY gene is responsible for the production of androgenes (male sex hormones) and this gene is linked to the Y-chromosome. (In some rare cases a child may; however, lack sensitivity of the androgenes and turn out an XY female as in the CAIS syndrome)
Since as many as 500.000 sperm cells are released during ejaculation it might seem random which one reaches the egg first. Some people claim, however, that the woman may influence this! The reason is that the Y chromosome is physically smaller than the X chromosome and therefore sperm cells containing a Y will have a tendency to move faster through the vagina and uterus. On the other hand sperm cells containing an X chromosome tends to survive a longer period of time. Together this means that sex close to the time of ovulation (which is usually 14 days before the next cyclus begins) is more likely to result in a male baby.
Though the male's sperm is responsible for determining the sex of a child at "conception" meaning the fertilization of the egg, the woman's vaginal conditions can determine which of the sperm (Y's or X's) are left for fertilization. The Y's are more fragile, so if the woman's body is more acidic and higher in temperature the more likely the X sperms will only survive.
The sperm from the father can supply either an X-bearing or a Y-bearing chromosome. The egg from the mother can only supply an X-bearing chromosome. An XY combination produces a boy baby. An XX combination produces a girl baby. It might seem that the father therefore determines the sex of the baby, but some recent evidence suggests that the mother can select either an X-bearing or a Y-bearing sperm. See the Wikipedia article on "Maternal influence on sex determination."
In reproduction, the woman donates an egg and the man donates a sperm. Each has only one sex chromosome, X or Y. The egg is always X. The sperm cell can contain an X or a Y chromosome. A person who is XX is female and a person who is XY is male.
Only he has the chromosome of both male and female hence determining weather the fetus will develop into a male or female.
Women carry XX and men carry XY. Every human is XX or XY. The baby gets an X from the mom and either the X or the Y from the dad.
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 of a child is determined by the father because the genes that determine sex come from the male sperm.
Sex, as in gender, is determined by the sex organs possessed by an individual. Genetic errors and mutations can make it difficult to determine by just this, but more sophisticated methods exist.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
The individual will have half of the mother's chromosomes and half of the father's chromosomes.
A skeleton does NOT determine gender. The chromosomes of an individual do that. However it is usually possible to determine the gender of a human skeleton by examination of the width of the pelvissciatic notchventral arca protrusions from the skull are more marked in males than femalesheight of the skeletonbone thickness (robustness)gracility of the skeleton
The sex chromosomes, X and Y, determine the gender of one's offspring. An X and a Y is a boy, and 2 X's is a girl.
In the context of gender, "father" is associated with masculinity as it typically refers to a male parent. This reflects societal norms and traditional gender roles where fathers are expected to exhibit characteristics and behaviours considered masculine.

Yes, girls can be bouncers. Gender does not determine a person's ability or suitability for the job. As long as an individual meets the necessary qualifications, such as physical strength and good judgment, they can work as a bouncer regardless of their gender.

The gender of a stepfather can be either male or female, depending on the individual's gender identity.
the way you determine a turtles gender is by looking at the claws males have longer claws then femals do ps hoped this helped.
The genes that determines gender can be found in the Y chromosome.
