How the sex of a person determined?
Human cells contain 23 pairs of chromosomes for a total of 46. There are 22 pairs of autosomes and one pair of sex chromosomes. The sex chromosomes are the X chromosome and the Y chromosome. If you are male you have the XY chromosome.. making you a male. If you are female you have the XX chromosome.. making you a female. It all depends on the father, if the father gives an X chromosome... you have a girl. Because it combines with the mother's X chromosome.. creating XX(a female) If the father give a Y chromosome.. you a have a boy. It combines with the mothers X chromosomes.. creating XY(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.
Explain how the sex chromosomes determine the sex of the offspring?
it is determined by which parent give the chromosome. if the y chromosome is in it will be a girl and if it will be a boy.
A child will be a girl if she receives what chromosomes from father and what chromosomes from mother?
A child's sex is actually determined entirely by his or her father. All eggs in a woman's body contain and X chromosome, whereas sperm cells contain either X or Y. The female sex chromosomes are XX and the male sex chromosomes are XY. Thus, if the sperm that fertilizes the egg contains an X chromosome, the child will be a girl. If the sperm contains a Y chromosome, the child will be a boy.
What sex is more likely to get a sex-linked disorder?
Many sex-linked disorders come from the X chromosome. (Either gender can obtain the disorder, however, it is harder for a female to get it than a male). Very few sex-linked disorders occur on the Y chromosome. (Only males can obtain these disorders).
Can parents pick if they want a boy or a girl?
Unfortunately, no they cannot. It depends on the mother chromosomes (XX) and the father chromosomes(XY). The chromosomes from the father is basically the only chromosomes to detect the sex of the baby. Boy or Girl. If a mother's X chromosome meets with the fathers X chromosome, it will be a girl. If a mothers chromosome X meets with the father Y chromosome, it will be a boy.
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 are the X and Y chromosomes?
Everybody has 23 pairs of chromosomes, half they get from their mother and half from their father. The 23rd chromosome you have contains the information of what sex you are. If you are a girl you will have a X chromosome from your mother and and X chromosome from you father. If you are a boy it means you will have a X chromosome from your mother and a Y chromosome from your father. When a sperm cell fertilises an egg the sperm will either be carrying the X chromosome from the male or a Y. If the sperm is carrying a X it will pair with the X chromosome from the mother making the baby a girl. If the sperm is carrying a Y chromosome it will pair with the X chromosome from the mother making the baby a boy! This means it is all down to the father whether the baby is a boy or a girl.

Why is genotype of the father unimportant when investigating sex-linked traits inherited by male offspring?
Fathers pass the Y sex chromosome to their sons, NOT the X sex chromosome.
