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.
Chromosomes in the nucleus contain genes. DNA contains the information that we call a gene. A gene is a region of DNA on a chromosome that contains the information needed by the cells ribosomes to create a protein.
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.
No. The human X chromosome contains over 1000 genes, many of which are essential for life. The Y chromosome in comparison has only about 120 genes. A zygote with Y0 or YY (one or two Y chromosomes) would not be viable.
The genes that are carried on the same chromosome are called as the linked genes.
The y chromosome, which only contains a few hundred genes.
Can each chromosome usually contain multiple genes? yes each chromosome usually contains more than one gene.
Genes that are location on the sex chromosomes.

There are thousands of genes in a chromosome.

Both X and Y chromosomes i.e. Allosome 23rd pair contains sex linked genes.
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
Chromosomes in the nucleus contain genes. DNA contains the information that we call a gene. A gene is a region of DNA on a chromosome that contains the information needed by the cells ribosomes to create a protein.
The DNA molecules in various combinations form the genes which are the genetic code of a chromosome.
