What conditions can aneuploidy of sex chromosomes cause?
An example of aneuploid condition is Down syndrome, is due to three copies of choromosome 21 or trisomy 21.
What mutation cause changes in the number of chromosome?
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.
A situation in which chromosome number can be represented as either 2n plus 1 or 2n-1 is called?
A situation in which the chromosome number can be represented as either 2n plus 1 or 2n-1 is called aneuploidy. Aneuploidy refers to an abnormal number of chromosomes, either an extra or a missing chromosome, compared to the normal diploid number. This can lead to genetic disorders and developmental abnormalities.
Polyploidy instantly results in a new plant species because it?
changes a species' number of chromosomes.:) no problem
What is the number of chromosomes in a gemete?
Depends on what species is in questions - different species have different numbers of chromosomes in gametes.

What mutation cause changes in the number of chromosome?
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.
What is an aneugen?
An aneugen is an aneugenic agent, an agent which induces aneuploidy, the state of possessing a number of chromosomes which is not an exact multiple of the haploid number.
What happens when a fetus has 3 cromizones instead of 2?
a "normal" human being should have a total of 46 chromosomes. 23 from mom, 23 from dad. if something goes wrong during meiosis, the chromosomes may not be separated normally and a gamete (sex cell, known as sperm or egg) will have either too few or too many chromosomes. this is known as aneuploidy. the effects of aneuploidy on the zygote will vary depending on what chromosomes you are talking about. in the case of chromosome #21, having one extra is called "trisomy 21" which leads to the condition known as down syndrome. chromosome pairs 1-22 are a person's autosomes. the 23rd pair are sex chromosomes. aneuploidy affecting the sex chromosomes can have various effects, depending on what chromosomes are inherited. as you can see, the effects of aneuploidy depend on the specific chromosome number/pair. aneuploidy usually is not fatal.

Does every species has a characteristic number of chromosomes?
Yes they do. Some species have the same number of chromosomes but not all.
What is the species number of chromosomes in humans?
46 Chromosomes

Do all species have the same number of chromosomes?
No, chromosomes vary from species to species. A species is distinguished by individuals that can mate and have young that are capable of producing offspring. The number of chromosomes two individuals have must be the same for this to be possible.
What is the number of chromosomes in the nucleus?
It varies from species to species. The human nucleus contains 46 chromosomes.
What is the number of chromosomes in a gemete?
Depends on what species is in questions - different species have different numbers of chromosomes in gametes.
What chromosomes can be affected by changes in chromosome numbers?
Any chromosome can be affected by aneuploidy. However, generally, the larger the chromosome, the larger the likelihood that the change in chromosome number will be fatal.
