What else can I help you with?
When chromosome pair fail to separate properly during meiosis the error is called?
Nondisjunction.
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.
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 during meiosis do sister chroamtids separate?
Sister chromatids separate during anaphase II of meiosis.
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 are the consequences of the failure of chromosomes to separate properly during meiosis?
When chromosomes fail to separate correctly during meiosis, it can lead to genetic disorders in offspring, such as Down syndrome or Turner syndrome. This can result in physical and developmental abnormalities, impacting the health and well-being of the individual.
Down Syndrome most often occurs when-?
Down Syndrome often occurs when chromosomes fail to separate properly during 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.
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.
If nondisjunction occurs during meiosis?
It is the failure of chromosome pairs to separate properly during cell division.
What is a genetic condition that can result when chromosomes don't separate correctly during meiosis?
Trisomy 21 (Down's syndrome), Turner's syndrome (XO), and Klinefelter's syndrome (XXY) are a few examples of genetic disorders that can result when chromosomes don't separate correctly during meiosis.
Which is the failure to segregate during meiosis?
Nondisjunction is the failure to segregate homologous chromosomes or sister chromatids properly during meiosis, leading to an incorrect number of chromosomes in the resulting gametes. This can result in genetic disorders such as Down syndrome.

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.
If a child is born with down syndrome when did the mutation occur?
During meiosis
How are cells of a person with Down syndrome different from those of a person without the disorder?
In Down syndrome, a person's cells have an extra copy of chromosome 21. In other words, instead of a pair of chromosomes, a person with Down syndrome has three of that chromosome. Down syndrome most often occurs when chromosomes fail to separate properly during meiosis. People with Down syndrome have a degree of mental retardation. Heart defects are also common, but can be treated.
