Question: Which syndrome or condition represents Monosomy?

Turner syndrome is a genetic condition caused by an abnormality on one of your sex chromosomes. It’s also called monosomy X, gonadal dysgenesis, and Bonnevie-Ullrich syndrome. Only the female sex develops this condition. Turner syndrome occurs when part or all of one of your X chromosomes is missing.

Which condition represents monosomy?

About half of all girls with Turner syndrome have a monosomy disorder. 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.

What is an example of monosomy?

Monosomy: Missing one chromosome from a pair. For example, if a female has one X chromosome (X monosomy) rather than two, she has Turner syndrome.

Is XXY syndrome monosomy or trisomy?

Monosomy is the presence of only one member of a chromosome pair in a karyotype. It is generally more detrimental to embryonic and fetal development than is the equivalent trisomy. Monosomy may result from nondisjunction or chromosome lag.

Which is an example of monosomy in humans?

Examples of monosomy in humans are Turner syndrome (usually with one X chromosome only and the other is missing), cri du chat syndrome (where the end of the short p arm of chromosome 5 is missing), and 1p36 deletion syndrome (where the end of the short p arm of chromosome 1 is missing).

Which monosomy is compatible with life?

Human monosomy

Turner syndrome is the only full monosomy that is seen in humans — all other cases of full monosomy are lethal and the individual will not survive development.

Is Jacob’s syndrome monosomy or trisomy?

(Lewis, 246) Also referred to as ‘Trisomy 18. ‘ Jacobs Syndrome: male with an extra Y chromosome. One male in 1,000 has an extra Y chromosome.

In general, a monosomic for a particular chromosome is more severely abnormal than is the corresponding trisomic.

CAN XXY have babies?

It is possible that an XXY male could get a woman pregnant naturally. Although sperm are found in more than 50% of men with KS3, low sperm production could make conception very difficult.
