The l virus that usually causes mononucleosis is the "Epstein-Barr virus". However it can also be caused by "Cytomegalovirus".
Normally individuals are born with both chromosomes. If, by chance, one is born with only one chromosome this is called aneuploidy. Monosomy is a form of aneuploidy. This condition can cause cri du chat syndrome, turner syndrome, and 1p36 deletion syndrome.
Monosomy is when cells of the embryo contain 45 chromosomes instead of 46. Monosomy is a genetic defect caused by an incomplete set of chromosomes.
What causes a trisomy or monosmy condition is having three chromosesomes, trisomy, or one isolated chromosome, monosomy
Nondisjunction, which is the failure of chromosome pairs to separate properly during meiosis.
Monosomy X (Turner syndrome) is the only known survivable monosomy.
Monosomy occurs when one chromosome is absent from the normal diploid number. This is referred to as aneuploidy which is the loss or gain of a chromosome during meiosis.An example of monosomy is Turner Syndrome. One of the sex chromosomes is missing. In an unaffected female there are 2 'X' chromosomes. But in Turner Syndrome there is one sex chromosome missing.Trisomy occurs when there is three copies of a chromosome instead of the normal diploid number. This is also referred to as aneuploidy because there was an extra chromosome added hence, an abnormal amount of chromosomes.An example of trisomy is in Trisomy 21(Downs Syndrome) in which chromosome 21 has an extra chromosome.
It depends on what's missing. Zygotes missing a chromosome (monosomy) have 45 chromosomes and many do survive; some human monosomies are monosomy 7, 11 or 13. A monosomy X results in Turner syndrome; there must be at least one X chromosome, or the embryo won't survive.
Haploid refers to a cell that has has only one copy of each chromosome, like in a gamete such as a sperm cell or egg cell. Upon fertilization, the two haploids come together to form a full diploid cell (two copies of each chromosome) which then goes on to form the complete organism. Monosomy refers to a condition where there is only one copy of a specific chromosome. For example, in the human condition Turner Syndrome, there is only one X chromosome, instead of two sex chromosomes. Most incidences of monosomy other than Turner Syndrome are lethal, so there aren't many examples of it.
Turner's syndrome is a sex-linked monosomy. In this case, the person has only one X and no second X or Y.

Nothing 'causes' Turner Syndrome it is simply random geneticsGenetic mosaicism is most often implicated alongside nondidjunction and partial 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
45
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
deletion-occurs when an end of a chromosome breaks off or when two simultaneous breaks lead to the loss of an internal segment
monosomy.
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.
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.
