Best answer: Which is the only chromosome you can live without?

Can you live with only one chromosome?

Monosomy means that a person is missing one chromosome in the pair. Instead of 46 chromosomes, the person has only 45 chromosomes. This means a girl with TS has only one X chromosome in her 23 rd pair. Sometimes an error occurs when an egg or sperm cell is forming.

What happens if you dont have chromosome 1?

1 microdeletion is inherited in an autosomal dominant pattern, which means that missing genetic material from one of the two copies of chromosome 1 in each cell is sufficient to increase the risk of delayed development, intellectual disability, and other signs and symptoms.

Can a human survive with 45 chromosomes?

Turner syndrome is due to a chromosomal abnormality in which all or part of one of the X chromosomes is missing or altered. While most people have 46 chromosomes, people with TS usually have 45.

Turner syndrome
Duration Long term
Causes Missing X chromosome
Diagnostic method Physical signs, genetic testing

What is the function of chromosome 1?

Chromosome 1 likely contains 2,000 to 2,100 genes that provide instructions for making proteins. These proteins perform a variety of different roles in the body.

What happens if you have less than 46 chromosomes?

These changes can occur during the formation of reproductive cells (eggs and sperm), in early fetal development, or in any cell after birth. A gain or loss in the number of chromosomes from the normal 46 is called aneuploidy. A common form of aneuploidy is trisomy, or the presence of an extra chromosome in cells.
