In humans females are homogametic and males are heterogametic. It is the male biological parent who contributes the sex chromosome that determines the sex of any child.
Human females are XX and all their ova carry an X chromosome. Females always give their children an X chromosome.
Human males are XY and half their spermatozoa carry an X chromosome and half carry a Y chromosome. Depending on the sex chromosome in its biological father's spermatozoon, a child receives an X or a Y chromosome from its biological father.
If a child receives an X chromosome from its father she will be XX and a girl. If a child receives a Y chromosome from its father he will be XY and a boy.

Which gamete determines the gender of the offspring in homosapians?
The sperm gamete determines the gender of the offspring in humans. Sperm carries either an X or a Y sex chromosome, while the egg always contains an X chromosome. If a sperm with an X chromosome fertilizes the egg, the offspring will be female (XX). If a sperm with a Y chromosome fertilizes the egg, the offspring will be male (XY).
Which parents gamete normally determines the sex of the child?
The father's gamete determines the sex of the child. Specifically, the presence or absence of a Y chromosome in the father's sperm will determine if the child will be male (Y chromosome present) or female (no Y chromosome).
Where are the genes that determine gender found?
The genes that determines gender can be found in the Y chromosome.
What does the x and the y choromosome determine?
it determines the gender of a human being
How much does The male and female gamete each contribute zygotes DNA material?
The male gamete (sperm) and female gamete (egg) each contribute half of the genetic material required to form a zygote. Specifically, each gamete contains 23 chromosomes, so when they fuse during fertilization, the zygote ends up with a complete set of 46 chromosomes. This combination of DNA from both parents determines the genetic makeup of the offspring.
Which gamete determines the gender of the offspring in homosapians?
The sperm gamete determines the gender of the offspring in humans. Sperm carries either an X or a Y sex chromosome, while the egg always contains an X chromosome. If a sperm with an X chromosome fertilizes the egg, the offspring will be female (XX). If a sperm with a Y chromosome fertilizes the egg, the offspring will be male (XY).
Who makes the sex of the baby?
The chromosome in the male's gamete determines the gender of the baby. If it is a Y chromosome, the baby will be a boy. If the chromosome is a X, the baby will be a girl.
If a human gamete with an extra chromosome participated in fertilization with a normal human gamete what condition results?
A trisomy. Trisomies are usually fatal in all chromosome pairs except 5, 13, 21 (these cause Down syndrome), and 23 (The chromosome pair that determines gender)
Which parent's gamete decides the gender of a child?
The Father's.
Which kind of cell determines the sex of a child?
The sperm cell, which is a gamete.
Which parents gamete normally determines the sex of the child?
The father's gamete determines the sex of the child. Specifically, the presence or absence of a Y chromosome in the father's sperm will determine if the child will be male (Y chromosome present) or female (no Y chromosome).
Where are the genes that determine gender found?
The genes that determines gender can be found in the Y chromosome.
Which pair of chromesomes determines gender?
Chromosome pair 23 determines the gender of a human. These chromosomes will either be two X's for females, or an X and a Y for males.
What are some unusual characteristics of a stingray?
They have a fin, which determines, if their gender
The risk factor that also determines an individual's sex is?
gender
What does the x and the y choromosome determine?
it determines the gender of a human being
Is it true or false that the 23rd chromosome pair determines the gender of a child?
TRUE.
