Does a doubled chromosome have one original and one copy?
TRUE
What are bits of DNA that have been repeatedly copied from one chromosome to another referred to as?
Transposable elements, or transposons, are bits of DNA that have been repeatedly copied from one chromosome to another. These elements can move within the genome, causing genetic mutations and playing a role in genome evolution.
What happens in meiosis one that does not occur in meiosis two?
DNA is copied
One half of a duplicated 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.
What is it called when one person has three copies of one chromosome?
trisonomy

In one kind of abnormal chromosome inheritance called?
In one kind of abnormal chromosome inheritance called Down syndrome, a child has three copies of Chromosome 21!

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.
What are genes that are located on one sex chromosome but not the other called?
Genes that are located on one sex chromosome but not the other are called sex-linked genes.
What is it called when one person has three copies of one chromosome?
trisonomy
How does a bacterial chromosome go through replication?
When strands separate and each are copied, the daughter genome gets one parental strand and one newly synthesized complementary copy.
What is cell with one of each kind of chromosome?
If you mean haploid, as in half of each chromosome, or containing only one chromatid from each full chromosome, thenthe cell is called haploid.
In one kind of abnormal chromosome inheritance called down syndrome a child has three copies of what?
chromosome 21
What are the two halves of a double chromosome structure called?
The two halves of a chromosome are called chromatids, or, more fully, sister-chromatids.Each sister-chromatid contains one molecule of DNA. The two DNA molecules of one chromosome are, barring occasional copying errors, genetically identical, because they were formed from the same original DNA molecule at the most recent replication.
Is Down syndrome a single gene or polygenic trait?
Down syndrome is a result of having an extra chromosome in one's genes. Chromosome thirteen* if your that much into the science. It is also called trisomy 21 because the chromosome 21 is the one with the abnormalities. *Abnormalities with chromosome thirteen is called Patau syndrome or trisomy 13.
