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.

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).
Which sex chromosome determines if an offspring is male or female in humans?
In humans, which sex chromosome determines if an offspring is a male or female?
What determines weather a child concieved is a boy or a girl?
The sex of a child is determined by the sex chromosome of the sperm cell (which comes from the father). If it is a Y, the child will be a boy, if it is an X, the child will be a girl.
What gamete determines the sex of a child?
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."
Whose sex chromosomes determine a child's sex?
The sex chromosomes that determine a child's sex are inherited from the biological parents. The father contributes either an X or a Y chromosome, while the mother always contributes an X chromosome. The combination of these chromosomes determines the child's sex, with XX resulting in a female and XY resulting in a male.
Which gamete determines the gender of the young?
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.
What gene determines if a child will be a boy or girl?
The sex of a child is determined by the sex chromosome present in the father's sperm cell. If he donates an X, the child will be a girl, if he donates a Y, the child will be a boy. The historical or ancestral lineage doesn't have anything to do with the child's sex.
A male child will inherit what chromosome?
Most males have XY chromosomes while most females have XX chromosomes.
Who determines the sex of a child?
The generally accepted theory is that males determine the sex because males can donate both an X chromosome or Y chromosome, while females can only donate an X chromosome to their offspring :D Hope this Helped
In human which sex chromosome determines if an offspring is a male or female?
In humans, which sex chromosome determines if an offspring is a male or female?
What has alleles that are passed parent to child on a sex chromosome?
Sex-linked traits have alleles that are passed from parent to child on a sex chromosome.
How is the sex of a child determined in humans?
The sex of a child in humans is determined by the combination of sex chromosomes inherited from the parents. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of a Y chromosome determines male development, while the absence of a Y chromosome results in female development.
