If nondisjunction occurs, abnormal numbers of chromosomes may find their way into gametes, and a disorder of chromosome numbers may result.
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 during the separation of chromosomes in either meiosis or mitosis, leading to an abnormal number of chromosomes in the resulting cells.
Nondisjunction during mitosis can lead to aneuploidy, where cells have an abnormal number of chromosomes, which can result in developmental abnormalities or cell death. If an individual has somatic cells with nondisjunction, it can lead to mosaicism, where different cells in the body have different chromosome numbers, potentially causing genetic disorders or health issues.
No, achondroplasia is not caused by nondisjunction. Achondroplasia is a genetic disorder caused by a spontaneous mutation in a gene involved in bone growth. Nondisjunction is a genetic event that occurs during cell division and can lead to abnormal chromosome numbers in offspring.
It is the failure of chromosome pairs to separate properly during cell division.

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.
Nondisjunction occurs during anaphase, usually when referring to meiosis, when a tetrad fails to separate.
Nondisjunction
If nondisjunction occurs during meiosis, it results in the improper separation of chromosomes, leading to gametes with an abnormal number of chromosomes. When these gametes fuse during fertilization, the resulting zygote may have an extra chromosome (trisomy) or a missing chromosome (monosomy). This can lead to genetic disorders, such as Down syndrome, which is caused by an extra copy of chromosome 21. Nondisjunction can occur in either meiosis I or meiosis II, with differing impacts on the resulting gametes.
The three types of nondisjunction are autosomal nondisjunction, sex chromosome nondisjunction, and structural chromosome nondisjunction. Autosomal nondisjunction involves the failure of homologous chromosomes to separate during cell division. Sex chromosome nondisjunction involves the failure of sex chromosomes to separate. Structural chromosome nondisjunction involves the incorrect separation of chromosome parts during cell division.
yes . it is . nondisjunction is takes place during meiosis.
