RNA molecules
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.
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.
linked genes
There are different types of genes for encoding three types of RNA. Protein coding genes are transcribed by RNA polymerase II to yield mRNA. Ribosomal RNA (rRNA) are transcribed by RNA polymerase I. Likewise, transfer RNA (tRNA) are transcribed by polymerase III.

X and Y
There are thousands of genes in a chromosome.
Chromosome
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.
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 number of genes varies. Most of any chromosome consists of non-coding DNA, which does not contain any genes. Each chromosome has many chromatins. One gene consists of many chromatins. Therefore, one chromosome could have many genes.
The DNA molecules in various combinations form the genes which are the genetic code of a chromosome.
