homologous chromosomes fail to separate during meiosis
Nondisjunction occurs during the separation of chromosomes in either meiosis or mitosis, leading to an abnormal number of chromosomes in the resulting cells.
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.
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 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.
Nondisjunction is a chromosomal abnormality that results in the failure of homologous chromosomes or sister chromatids to separate properly during cell division. This can lead to an uneven distribution of chromosomes in daughter cells, causing genetic disorders or conditions such as Down syndrome.
What occurs during nondisjunction
Nondisjunction
Nondisjunction is an error in cell division that can lead to an abnormal number of chromosomes in a cell. When nondisjunction occurs in germ cells, it can be inherited by offspring, leading to genetic disorders such as Down syndrome. The risk of inheriting nondisjunction increases with parental age.

Nondisjunction is the term used for when homologous chromosomes fail to separate during meiosis, resulting in an abnormal number of chromosomes in the resulting gametes. This can lead to genetic disorders in offspring due to an incorrect number of chromosomes.
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.
Nondisjunction occurs during anaphase, usually when referring to meiosis, when a tetrad fails to separate.
It is the failure of chromosome pairs to separate properly during cell division.
