Which chromosome contains less genes?

But while the X chromosome has remained large throughout evolution, with about 2000 genes, the Y chromosome lost most of its genetic material early in its evolution; it now retains less than 100 of those original genes.

Which is the largest gene?

The largest known gene is the human dystrophin gene, which has 79 exons spanning at least 2,300 kilobases (kb).

Which chromosome in human genome has more genes?

Our genetic information is stored in 23 pairs of chromosomes that vary widely in size and shape. Chromosome 1 is the largest and is over three times bigger than chromosome 22. The 23rd pair of chromosomes are two special chromosomes, X and Y, that determine our sex.

How many genes does the Y chromosome have?

The Y chromosome likely contains 50 to 60 genes that provide instructions for making proteins. Because only males have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and development.

Who has more genes males or females?

The human genome

Men and women have practically the same set of about 20,000 genes. The only physical difference in their genetic make up is in the sex chromosomes. Only males have a Y chromosome. Although the X chromosome is present in both sexes, there are two copies in females and only one in males.

Which is the smallest gene?

Chromosome 21 is both the smallest human autosome and chromosome, with 48 million base pairs (the building material of DNA) representing about 1.5 percent of the total DNA in cells.

Chromosome 21
Chromosome 21 pair in human male karyogram.
Length (bp) 46,709,983 bp (GRCh38)
No. of genes 215 (CCDS)

How big is the DMD gene?

The dystrophin gene is the largest known human gene, containing 79 exons and spanning > 2,200 kb, roughly 0.1% of the whole genome (96). The most common mutation responsible for DMD and BMD is a deletion spanning one or multiple exons.

What is the titin gene?

The TTN gene provides instructions for making a very large protein called titin. This protein plays an important role in muscles the body uses for movement (skeletal muscles) and in heart (cardiac) muscle. Slightly different versions (called isoforms) of titin are made in different muscles.
