In humans, the sex chromosomes are designated as X and Y. The X chromosome is larger than the Y chromosome and contains more genes, playing a crucial role in various biological functions and traits. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY), which leads to differences in genetic expression and inheritance patterns between the sexes.
What else can I help you with?
In humans the shorter of the sex chromosomes?
In humans, the Y chromosome is noticeably shorter than the X chromosome.
In humans what are the chromosome pairs 1 through 22 called?
Chromosome pair 23 in humans is the pair of sex chromosomes. In females, both sex chromosomes are the X sex chromosome, and in human males one sex chromosome is the X and the other is the Y chromosome.

Why is the 23rd pair of chromosomes not always homologous?
The 23rd pair of chromosomes are the sex chromosomes. In female humans, both sex chromosomes are homologous, and characterized as XX. In male humans, one sex chromosome is an X chromosome and the other is a much smaller, nonhomologous Y chromosome, and is characterized as XY.

If a characteristic is sex-linked then where is the gene for it found?
Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
Do Males or Females have a larger sex chromosome?
males
What sex chromosome is present in all humans?
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.

What is the sex chromosome pair in humans?
XX = femaleXY = maleThe X and Y chromosomes, the X being much larger than the Y, but the Y carries the sex determining region, the SRY.
