A duplicated chromosome consists of two identical sister chromatids joined at the centromere. Therefore, one half of a duplicated chromosome refers to one of these sister chromatids, which contains a copy of the genetic material from the original chromosome.
One copy will be made totalling 2 of the same chromosome, one for each cell.
A homologous strand of a chromosome is a duplicated copy of the original chromosome, formed during DNA replication. It contains the same genetic information as the original chromosome and is held together by a centromere. Homologous chromosomes play a key role in meiosis, where they pair up and exchange genetic material during crossing over.
monosomy. This term refers to the condition where an individual is missing one copy of a particular chromosome and only has one copy instead of the normal two.
If nondisjunction occurs in meiosis II for one chromosome, the result would be that one gamete receives an extra copy of the chromosome and one gamete lacks that chromosome. This results in aneuploidy in the offspring, which can lead to genetic disorders such as Down syndrome.
A chromatid means one copy, or a daughter cell, of a duplicated chromosome, which is joined to another copy by a single centromere. Each contain the same DNA and chromosome protein as the original cell.
Aneuploid - the individual has an extra copy of one chromosome or is missing a chromosome.
A duplicated chromosome consists of two identical sister chromatids joined at the centromere. Therefore, one half of a duplicated chromosome refers to one of these sister chromatids, which contains a copy of the genetic material from the original chromosome.
One copy will be made totalling 2 of the same chromosome, one for each cell.

Hemizygous. This term is used to describe males who have only one copy of a gene located on the X chromosome since they have only one X chromosome.
The process of mitosis ensures that each new eukaryotic cell receives a copy of each chromosome. During mitosis, the chromosomes are duplicated and then segregated equally into two daughter cells. This ensures that each daughter cell receives a complete set of chromosomes.
Yes.
If a person is missing a chromosome, it is known as monosomy. Monosomy occurs when there is only one copy of a particular chromosome instead of the usual two copies. For example, a person missing one copy of chromosome 21 would have a condition called monosomy 21 or trisomy 21, which is also known as Down syndrome.
