Small errors or errors in insignificant parts of the chromosome may lead to no problems, but as the errors increase in size/scope you start having problems. Errors may cause proteins to have problems, causing property changes (shape, charge areas), functional changes (no longer able to catylize reactions), or even become problematic for the cell (buildup of junk, pirons). That, as well as other changes to the chromosome, may trigger apoptosis (cell death), mark for destruction by white blood cell, proliferation (cancer), and other transformations.

What organisms with three or more sets of chromosomes called?

Organisms with three or more sets of chromosomes are called polyploids. This can occur in plants and some animals, where multiple sets of chromosomes are present in each cell. Polyploidy can result from errors in cell division or hybridization between different species.


Can nondisjunction occur during mitosis?

Yes, nondisjunction can occur during mitosis. Nondisjunction is the failure of chromosomes to separate properly during cell division, leading to an abnormal distribution of chromosomes in the daughter cells. This can result in genetic disorders such as Down syndrome.


Does meiosis result in the doubling of chromosomes?

No, meiosis does not result in the doubling of chromosomes. Instead, it reduces the number of chromosomes in a cell by half.


In Jacob syndrome did the nondisjunction occur in the mother or father?

Jacob syndrome, 49XYY, has to occur as a result of nondisjunction in the father. The Jacob Syndrome male would have received the X chromosome from his mother, and both Y chromosomes from the father (since the Y chromosomes can not possibly have come from the mother). Jacob Syndrome can be the result of nondisjunction in meiosis.


What would happen if homologous chromosomes did not pair in prophase 1?

If homologous chromosomes did not pair in prophase I of meiosis, it could result in improper segregation of chromosomes during meiosis, leading to aneuploidy in the daughter cells. This could result in genetic disorders or developmental abnormalities in offspring.

Does chiasmata occur in mitosis?

No, chiasmata do not occur in mitosis. Chiasmata are structures that form during meiosis, specifically during prophase I, as a result of crossing over between homologous chromosomes. Mitosis does not involve homologous chromosomes pairing up and exchanging genetic material like in meiosis.

Duplication of chromosomes occur in?

The replication of the chromosomes occurs during interphase.


What are sex chromosomes that result in male?

XY Chromosomes = Males XX Chromosomes = Females


Why do karyotypes always show chromosomes at the point when cell division is about to occur?

They show chromosomes at the point when cell division is about to occur because the chromosomes are condensed and aligned which makes it easy to tell if there are the correct number and configurations of the chromosomes.


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.

Homologous chromosomes occur during meiosis. Meiosis reduces the chromosome number by half.
