Additional chromosome
What is Monosomy?
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.
What type of genetic disorder is PKU?
PKU is described as an inherited, autosomal recessive disorder.
Why can women be a sex-linked genetic disorder but a male cannot?
Women can carry or have a sex linked (x-linked) genetic disorder. Males cannot be carriers, they either have the disorder or they don't: this is because the male has only one X chromosome.
How can genetic counselors predict genetic disorders?
Well certain disorders are found on certain chromosomes and on certain parts of the chromosome. How they find out how, i don't know. But if some pieces of a specific chromosome they can predict they will have a certain disorder
What does monosomy mean?
Monosomy is a genetic condition characterized by the presence of only one copy of a particular chromosome instead of the normal two. This can lead to various developmental and health issues, depending on which chromosome is affected. A well-known example of monosomy is Turner syndrome, where there is a missing X chromosome in females. Monosomy can occur due to errors in cell division during meiosis or mitosis.
What is monosomy 21?
Monosomy 21 refers to a genetic condition where an individual is missing one copy of chromosome 21, resulting in a total of only one chromosome instead of the normal pair. This condition is extremely rare and is often associated with severe developmental and physical challenges. Unlike Down syndrome, which is caused by an extra copy of chromosome 21 (trisomy 21), monosomy 21 typically leads to more severe clinical outcomes and is usually not compatible with life.
How many chromosomes does a human with monosomy have?
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.
Is Down syndrome a genetic disorder or a chromosome disorder?
Down syndrome is a chromosomal disorder. It is caused by having 1 extra chromosome (chromosome 21).
What accurately describes monosomy?
Monosomy is a genetic condition characterized by the absence of one chromosome from a pair, resulting in an individual having a total of 45 chromosomes instead of the normal 46. This condition can lead to various developmental and health issues, depending on which chromosome is missing. A well-known example of monosomy is Turner syndrome, where there is a complete or partial absence of one X chromosome in females. Monosomy can arise from errors during cell division, particularly during meiosis.
What causes monosomy?
The l virus that usually causes mononucleosis is the "Epstein-Barr virus". However it can also be caused by "Cytomegalovirus".
Can a raccoon have Down's syndrome?
No, Down's syndrome is only a human genetic disorder. Those with the disorder have an extra chromosome. Raccoons do not get this particular genetic disorder.

Why is monosomy worse than trisomy?
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.
Why can a man who has a sex-linked disorder pass the disorder to his daughters but not to his sons?
Sounds like the disorder is genetic and located in his x-chromosome.

Why are trisomy zygotes more likely to survive than monosomy individuals?
Trisomy zygotes typically have an extra chromosome, providing an extra copy of genetic material which can compensate for any missing genes and help maintain normal cellular function. Monosomy individuals, on the other hand, lack one chromosome which can lead to more severe genetic abnormalities and developmental issues, making survival less likely.
