All organisms carry a set number of pairs of chromosomes, in humans it is 23 pairs. Of these chromosomes one pair controls the sex of the human. The sex chromosomes are called the X and Y chromosome. Females have XX pairing and Males XY.

What sex chromosome does a human egg cell contain?
The sex chromosome typically carried by an ovum is X-chromosome. The sperm may carry either x or y sex chromosome.
Do men carry only XX chromosomes?
Men typically have one X chromosome and one Y chromosome. Women typically have two X chromosomes. So-called XX males have two X chromosomes; thus they are genetically female but otherwise appear to be male.
Why does the y chromosome not carry any alleles?
The Y chromosome is smaller than the X chromosome and contains fewer genes. It carries the genes necessary for determining male sex and some other genes, but it lacks many of the genes present on the X chromosome. This is why the Y chromosome does not carry any alleles in the same way that the X chromosome does.
What is a non example of chromosome?
An example could be mitochondria, because 1. Its not a chromosome and 2. It doesn't carry chromosomes.
Why x chromosome is placed in group c and y chromosome placed at the end of forth row?
the y chromosome doesn't carry any genetic information

What type of chromosome always carry gene for the same trait at the same location on both chromosome?
homologous chromosomes

Why x chromosome is placed in group c and y chromosome placed at the end of forth row?
the y chromosome doesn't carry any genetic information
Which gamete has the chromosome that determines a person's sex?
Females carry the XX Chromosome and Males Carry The XY chromosome A sex cell contains half of this chromosome (so for Me either X or Y and for women either one of the Xs). There for it is the mans sperm with determines the sex of the child as a woman can only give X where as a male can give either X or Y. X to have a girl and Y for a boy.
What are the x and y chromazones?
The Y chromosome is the male sex chromosome, but males also carry a X chromosome from their mother. XY. The female sex chromosome is the Y chromosome; YY is female. ( generally, as sex chromosome number in both sexes can vary )
What is the Specific units of a chromosome that carry individual traits?
genes
What chromosomes carry triple x syndrome?
chromosome 21
Why is a human cell containing 22 autosomes and a y chromosome a sperm?
Human somatic (body) cells contain two sets of 23 chromosomes. Human gametes (sperm and egg cells) contain one set of 23 chromomes -- 22 autosomes and 1 sex chromosome. Only a sperm cell can carry a y chromosome. A sperm cell can also carry an x chromosome. The ovum can carry only an x chromosome, never a y chromosome. So a cell containing 22 autosomes and a y chromosome must be a sperm cell.
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.
