Short Answer = Yes.
Im trying to find the same anwser. Its for the bio workwsheet right? the reinforcement and study guide questions. Ya and btw if it helps Down syndrome can be caused by a polyploidy
Although it is incredibly rare, mistakes in meiosis can lead to favorable variations in organisms and populations.

Is 'mutations are beneficial to organisms' a true statement about mutations?
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
How many divisions will a cell with 16 chromosomes have during meiosis?
Even if there was that kind of sex cell, I don't think it would survive! Sex cells ALWAYS have 46 chromosomes. At the end of meiosis, as long as there are no mistakes, each sperm or egg cell would have 23 chromosomes.
What Meiosis occurs in .?
meiosis occurs in the overies and the testies.....there is 2 stage of meiosis...meiosis 1 and meiosis
Is a type of cell division that produce gametes?
That is meiosis.
Recombination occurs during?
meiosis
Can mistakes in meiosis ever be beneficial?
Mistakes in meiosis can be beneficial. These mistakes are considered nonlethal mutations in the DNA of the organism. A example of a good mutation would be the changing of a butterfly's wing color. If a parent butterfly produces an offspring with a different color pattern, this can be beneficial to the offspring. The color pattern may be darker. This could help it blend in with the environment and survive from predators. Essentially, a beneficial mistake in meiosis would be considered a form of natural selection where the offspring continues to evolve.
How is meiosis beneficial to the evolution of a species by natural selection?

Occurs during prophase 1 of meiosis?
Mistakes such as nondisjunction can occur during meiosis. This is the result of chromosomes failing to separate equally during either anaphase.
How can mistakes occur during meiosis?
Mistakes such as nondisjunction can occur during meiosis. This is the result of chromosomes failing to separate equally during either anaphase. Therefore each resulting cell will not get an equal number of chromosomes. This can result in diseases such as down syndrome (Trisomy 21, where there are 3 copies of the 21st chromosome present instead of the normal 2), or gender complications such as Klinefelter's (XXY) or Turner's (XO) syndromes.
What is routine checking in Auditing?
This is when you will go through everything occasionally. It allows for the chance to catch any mistakes or issues that may come up.

Which stage of meiosis causes Down syndrome?
Mistakes in meiosis may cause Down syndrome. The error happens when the chromosomes segregate into the gametes. The egg or sperm may have too many or too few chromosomes. Down syndrome has an extra chromosome in the 21st pair.

What are the two distinct stages of meiosis?
Meiosis I and meiosis II
What Meiosis occurs in .?
meiosis occurs in the overies and the testies.....there is 2 stage of meiosis...meiosis 1 and meiosis
Are Meiosis I and Meiosis II identical steps that follow each other?
If you mean meiosis I and meiosis II, then no they are not identical, but meiosis II does follow meiosis I.
Do jellyfish use mitosis or meiosis?
Meiosis
