What else can I help you with?
What causes disorders sush as klinefelter syndrome and turner syndrome?
non disjunction of sex chromosomes
The faillure of chromosomes to separate during meiosis is called?
The failure of chromosomes to separate during meiosis is called nondisjunction. This can result in an incorrect number of chromosomes in the daughter cells, leading to genetic disorders such as Down syndrome.
What is a failure of homologous chromosomes to separate in meiosis?
A failure of homologous chromosomes to separate in meiosis is called nondisjunction. This can result in cells with an abnormal number of chromosomes, leading to genetic disorders such as Down syndrome. Nondisjunction can occur during either the first or second division of meiosis.
What is the failure of chromosome pairs to separate properly during meiosis?
The failure of chromosome pairs to separate properly during meiosis is called nondisjunction. This can lead to an incorrect number of chromosomes in the resulting gametes, causing aneuploidy in the offspring. Aneuploidy can result in genetic disorders such as Down syndrome.
What happens if nondisjunction occurs during meiosos?
If nondisjunction occurs during meiosis the result could be a wide range of mutations. Most likely it would result in mosaicism meaning there will be a mixture of affected cells and non affected cells.
Nondisjunction occurs when?
Nondisjunction occurs when chromosomes fail to separate properly during cell division, resulting in an abnormal number of chromosomes in the daughter cells. This can lead to genetic disorders like Down syndrome, Turner syndrome, and Klinefelter syndrome.
Are there carrier forms of xxx syndrome?
no there r no carrier forms for triple x syndrome. this is just a nondisjunction during meiosis of gametogenesis. this can happen with either spermatogenesis or ovariogenesis
When chromosomes do not part in meiosis like they should?
When chromosomes do not separate properly during meiosis, it can lead to an incorrect number of chromosomes in the resulting gametes. This condition is known as nondisjunction and can result in genetic disorders like Down syndrome in humans.
If nondisjunction occurs during meiosis?
It is the failure of chromosome pairs to separate properly during cell division.
What is the medical term meaning abnormal condition of meiosis?
The medical term for an abnormal condition of meiosis is meiotic non-disjunction, which refers to the failure of chromosomes to separate properly during meiosis, resulting in an abnormal number of chromosomes in the resulting gametes. This can lead to conditions such as Down syndrome.
When do chromosomes separate abnormally in meiosis?
Chromosomes can separate abnormally in meiosis during a process called nondisjunction. This results in an uneven distribution of chromosomes in the sex cells, leading to an incorrect number of chromosomes in the resulting offspring. Nondisjunction can result in conditions such as Down syndrome.
Does Triple X syndrome occur because of nondisjunction?
Yes, Triple X syndrome can occur due to nondisjunction during meiosis, resulting in an individual having an extra X chromosome (47, XXX) instead of the typical two X chromosomes (46, XX). Nondisjunction can happen during either the mother's or father's gamete formation.
