Here are two examples that result in 'early fetal death' - Trisomy 13 and Trisomy 18. Meaning that when the normal [genetic] chromosomal complement is a chromosome pair, three copies of each chromosome are present and this is lethal.
Monosomy
yes my son is 3 months old and he has monosomy 21,they do say hes a miracle and not suppose to be here
The only monosomy that a human can have and still survive is Turner syndrome, which is characterized by having only one X chromosome (45,X). Individuals with Turner syndrome may have a range of symptoms, including short stature, infertility, and heart defects.
trisomy
A trisomy. A monosomy is when there is only one of a chromosome. A trisomy is when there are three of a chromosome. In Klinefelter's syndrome, there are three sex chromosomes.
Turner Syndrome
A loss of a complete chromosome is called monosomy. This occurs when a cell only has one copy of a particular chromosome instead of the usual two copies.
monosomy. This term refers to the condition where an individual is missing one copy of a particular chromosome and only has one copy instead of the normal two.
If a person is missing a chromosome, it is known as monosomy. Monosomy occurs when there is only one copy of a particular chromosome instead of the usual two copies. For example, a person missing one copy of chromosome 21 would have a condition called monosomy 21 or trisomy 21, which is also known as Down syndrome.
monosomy
If only one member of a pair of chromosomes is present in a cell, this is known as monosomy. Monosomy can result in genetic disorders and may lead to developmental abnormalities or health issues. An example of monosomy is Turner syndrome, where individuals have only one X chromosome instead of the typical two.
A human with monosomy has 45 chromosomes instead of the usual 46. This genetic condition results from the loss of one chromosome in a pair, leading to various health issues depending on which chromosome is affected.
