What is the result when there is an error during meiosis Brainly?

What is the result when there is an error during meiosis?

Errors during meiosis can lead to mutations in gametes. Defective gametes that undergo fertilization may result in miscarriages or ultimately lead to genetic disorders. The most likely mistake to occur during meiosis is chromosomal non-disjunction, which results in the wrong number of chromosomes in a sex cell.

What are some errors that can occur in meiosis?

Other mistakes that can occur during meiosis include translocation, in which part of one chromosome becomes attached to another, and deletion, in which part of one chromosome is lost entirely.

What will happen if the process of meiosis is unsuccessful?

If homologous chromosomes fail to separate during meiosis I, the result is no gametes with the normal number (one) of chromosomes.

What if it happens that there’s an error during cell division and mitosis?

Chromosome segregation errors during mitotic and meiotic cell divisions give rise to aneuploidy, an abnormal number of chromosomes. Aneuploidy can be frequently detected in the genome of cancer cells1 or individuals with developmental disorders, and is the leading cause of spontaneous miscarriages after fertilization.

What happens when you have an incorrect number of chromosomes?

A change in the number of chromosomes can cause problems with growth, development, and function of the body’s systems. These changes can occur during the formation of reproductive cells (eggs and sperm), in early fetal development, or in any cell after birth.

What are two types of errors in meiosis?

Inherited disorders can arise when chromosomes behave abnormally during meiosis. Chromosome disorders can be divided into two categories: abnormalities in chromosome number and chromosome structural rearrangements.

What errors can occur in mitosis?

Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans.

What can go wrong during meiosis quizlet?

What can go wrong during meiosis? A gamete can get the wrong number of chromosomes. Portions of a chromosome may be lost. Part of a chromosome can get inverted.

What would happen to a cell if it failed to complete meiosis II?

If sister chromatids fail to separate during meiosis II, the result is one gamete that lacks that chromosome, two normal gametes with one copy of the chromosome, and one gamete with two copies of the chromosome.
