How many genes are there in one chromosome?

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.

Why a man unable to pass on sex linked gene to his son?

It is because the Y chromosome does not contain many of the genes present in X chromosome

Does a chromosome contain many genes which are composed of protein?

all genes are composed of protein (amino acid chains) so the answer is yes, all of them.

Most sex-linked genes are found on which chromosome x y?

Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.

How many genes are in a single chromosome?

There are 100-1,000 genes found on a chromosome. MANY ... for PLATO

How many genes are in a chromosone?

How many genes are in a eukaryotic Cell?

While distinguishing the number of Chromosomes from the number of Genes; and noting that one Chromosome will contain thousands of individual Genes - along with the fact that Eukaryotic genomes come in various sizes - a eukaryotic Cell will "Typically" contain anywhere from 30,000 to 70,000 or more Genes.

Each chromosome usually contains?

each chromosome contains many genes.

Which is larger a chromosome or a gene How do you know?

How many genes are in one chromosome?


How many genes are on a chromosome?

It depends on the chromosome and species. Chromosomes come in different sizes and with different numbers of genes per chromosome. Gene number isn't necessarily dependent on how big the chromosome is, either. Human chromosome 19, for example, is one of the smaller human chromosomes but has the most genes.

Is the Y chromosome bigger then the x chromosome?

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.

Is chromosome a type of gene?

A chromosome is a collection of many genes and protein substrates upon which the genes are strung, rather like beads on a string.

How many genes are in a single human chromosome?


How many genes are in chromosomes?

Varies, depending on the chromosome

Why does the X and Y chromosomes pick genders?

They are the ones designated for determining gender. They contain the specific genes which are necessary for gender determination. It only takes 3 genes to determine which set of genitals someone has, and the genes that are specific to the Y chromosome (not that many since it is so small in comparison to the X chromosome) override the gender determination genes of the X-chromosome. In addition, there are also genes on the X chromosome that are related to brain function, particularly in the prefrontal cortex. There is no telling why genes related to vision (the cone cells) are also in the human X chromosome. But if the mother has a mutated version of these genes, her sons will be color blind. So that is another possible sex difference.

How many genes do cells obtain?

The number of genes varies from chromosome to chromosome and the number of chromosomes varies from species to species (from as few as 1 single chromosome per cell to as many 30,000 chromosome pairs per cell). Human cells have 23 chromosome pairs per cell.

Is y or x chromosome larger?

The x chromosome is much larger than the y chromosome and contains many more genes.

How many genes are ona human chromosome?

Why do human males have Y chromosomes?

The Y chromosome is one of the two sex chromosomes in humans (the other is the X chromosome). The sex chromosomes form one of the 23 pairs of human chromosomes in each cell. The Y chromosome spans about 58 million base pairs (the building blocks of DNA) and represents almost 2 percent of the total DNA in cells. Each person normally has one pair of sex chromosomes in each cell. The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes. Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. The Y chromosome likely contains between 70 and 200 genes. Because only males have the Y chromosome, the genes on this chromosome tend to be involved in male sexual determination and development. Many genes are unique to the X or Y chromosome, but genes in an area known as the pseudoautosomal region are present on both chromosomes. As a result, men and women each have two functional copies of these genes. Many genes in the pseudoautosomal region are essential for normal development. Genes on the Y chromosome are among the estimated 20,000 to 25,000 total genes in the human genome. There are many genetic conditions related to genes on the Y chromosome. (taken from:

Which has more base pairs a gene or a chromosome?

A chromosome has more base pairs than a single gene, because a chromosome carries many genes.

Can you live with a y-chromosome and no x-chromosome?

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.

Is a gene a complete chromosome?

No, chromosomes are made up of many genes

A chromosome contains many genes that are transcribed into different what?
