That would be the chromosome number 23.
Regarding the [sex] chromosome number 23, the female gametes always have a [haploid] X chromatid, whereas the male gametes are just as likely to possess a [haploid] X chromatid as they are to possess a [haploid] Y chromatid.

Testis-determining factor is found in or on?
Testis-determining factor (TDF) is found on the Y chromosome of mammals. It is a gene called SRY (sex-determining region Y) that plays a crucial role in the development of testes and the determination of male sex characteristics.
What is a z chromosome?
The Z chromosome is a sex chromosome found in birds, reptiles, and insects. In species with ZW sex determination, females have two Z chromosomes (ZZ) and males have one Z chromosome (ZW). The Z chromosome plays a role in determining the sex of an individual.
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.
In genetics what is the female sex chromosomes?
X chromosome
What is the role of sex chromosomes in the control of gender and inheritance of hemophilia?
There are two sex chromosomes - X and Y. A person with two X chromosomes is female and a person with one X chromosome and one Y chromosome is male. One sex chromosome is inherited from each parent, with the sperm determining a child's sex.Hemophilia is a sex-linked condition as these genes are located on a sex chromosome (i.e. Y chromosome). Males are hence more prone to hemophilia as they only have one X chromosome. The sons of a carrier female have a 50% chance of suffering from hemophilia. The daughters of a hemophiliac father and a carrier mother may be affected, where she receives an affected X from both parents.
What are chromosome not directly involved in determining the sex of in individual?
Autosomes
What are chromosome not directly involved in determining the sex of an indiviual?
Autosomes.
How are autosomes similar to sex chromosomes?
Sex chromosomes and autosomes are from the same chromosome, The chromosome has 46 chromosomes and 2 of them are sex chromosomes and the rest are called autosomes
What is the sry gene?
The SRY gene is a gene on the Y chromosome required for the development of testes. It stands for Sex determining Region on Y chromosome.
How does the X chromosome help in determining the sex of the baby?
It doesn't. We all have X chromosomes.
Testis-determining factor is found in or on?
Testis-determining factor (TDF) is found on the Y chromosome of mammals. It is a gene called SRY (sex-determining region Y) that plays a crucial role in the development of testes and the determination of male sex characteristics.
What is the difference between sex chromosome an autosomal chromosome?
the autosome do not control the sex organs . but the sex chromosome control the sex organs
What is a z chromosome?
The Z chromosome is a sex chromosome found in birds, reptiles, and insects. In species with ZW sex determination, females have two Z chromosomes (ZZ) and males have one Z chromosome (ZW). The Z chromosome plays a role in determining the sex of an individual.
What is the link between sex-linked disorders and sex chromosome disorders?
sex-linked is normally involving X chromosome sex chromosome normally involving Y 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.
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 condition is carried on a chromosome other then the sex chromosome?
The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.
