Meiosis, specifically during anaphase I and anaphase II. This is known as nondisjunction and it causes aneuploidy, such as trisomy 21
If the chromosome mutations fail, then it is most likely to lead to a sign of cancer, since chromosome has failed to mutate properly.
Aneuploidy mutation causes a change in the number of chromosomes. Aneuploidy occurs during cell division when the chromosomes do not separate properly resulting in a change in the number of chromosomes.
Nondisjunction is the failure of chromosome pairs to separate properly during cell division. This can result in an abnormal number of chromosomes in the daughter cells, which can lead to genetic disorders such as Down syndrome.
The failure of chromosomes to separate during mitosis results in one gamete that lacks a chromosome and another with 2 chromosomes. Gametes with improper number of chromosomes are called aneuploid gametes. Aneuploid gametes are the most common cause of spontaneous abortion and handfuls of other congenital disorders that varies depending on donors gamete content.
The process of chromosomes separating during cell division is called "chromosome segregation" or "chromosome disjunction." This ensures that each new cell receives the correct number of chromosomes.
If the chromosome mutations fail, then it is most likely to lead to a sign of cancer, since chromosome has failed to mutate properly.
Nondisjunction is a mutation where chromosomes fail to separate properly during cell division, leading to an abnormal number of chromosomes in daughter cells. Translocation is a mutation where a segment of one chromosome breaks off and attaches to another chromosome, potentially disrupting the normal genetic sequence.
Aneuploidy mutation causes a change in the number of chromosomes. Aneuploidy occurs during cell division when the chromosomes do not separate properly resulting in a change in the number of chromosomes.
homologous chromosomes separate.
chromosome pairs separate
chromosome pairs separate
Nondisjunction occurs in too many cells or too few cells causing defects

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.

The process of chromosomes separating during cell division is called "chromosome segregation" or "chromosome disjunction." This ensures that each new cell receives the correct 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.
