X and Y
Wiki User
∙ 11y agoThe 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.
The Y chromosome contains more than 59 million blocks of DNA and represents almost 2% of the total DNA in cells within the body. The Y chromosome contains between 20,000 to 25,000 genes within the human genetic make-up.
Genes are located along the length of chromosomes, which are organized into pairs in most cells. Each chromosome pair contains genes at specific locations called loci. The order of genes along a chromosome is known as the gene sequence.
All of them except the Y chromosome are the same.
No, a gene is a specific region of DNA that contains the instructions for making a particular protein or RNA molecule. A chromosome is a long strand of DNA that can contain many genes as well as other genetic material. Each chromosome may contain hundreds or thousands of genes.
The y chromosome, which only contains a few hundred genes.
True. Each chromosome is made up of DNA that contains multiple genes, the basic units of heredity that code for specific functional proteins.
Genes that are location on the sex chromosomes.

There are thousands of genes in a chromosome.
Chromosome
A chromosome contains many genes that are transcribed into different RNA molecules. These RNA molecules can serve as templates for protein synthesis or have other functions in the cell.
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.
Both X and Y chromosomes i.e. Allosome 23rd pair contains sex linked genes.
The Y chromosome is smaller than the X chromosome and carries fewer genes because it has lost many genes over evolutionary time. The Y chromosome primarily carries genes involved in male sex determination and development.
Genes are found within the DNA molecule, specifically within the chromosomes located in the nucleus of a cell. Genes are composed of segments of DNA that code for specific proteins or control the expression of other genes.
The DNA molecules in various combinations form the genes which are the genetic code of a chromosome.
