TRUE
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.

The original chromosome is referred to as the "parent" chromosome, while the copied chromosome is known as the "daughter" chromosome. During cell division, specifically in processes like mitosis and meiosis, the parent chromosome replicates to produce one or more daughter chromosomes. This ensures that genetic information is accurately transmitted to the daughter cells.
Hemizygous - has 1/1 copy of the allele Heterozygous - has 1/2 copies of the alleleHomozygous - has 2/2 copies of the allele
Mitosis results in two identical cells being produced from the original cell. A copy of each chromosome is made before the cell divides and one of each chromosome goes to each new cell.
