Answer:
A chromosome is an organized package of DNA found in the nucleus of the cell. Humans have 23 pairs of chromosomes--22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y.

Sounds like a trick question.
Maybe not. contamination is easy, but gloves are a barrier between other organic material on yourself (such as what you ate for lunch) and what you are testing.
Other than the fact your DNA will be different than another person’s DNA, if we assume you are theoretically free of debris of any kind, then your DNA would test the same always.
Note: any contamination after purifying extract for a small sequence can give false positives. There are repeat sequences possible that would interfere if you are testing a small enough sequence.
I hope that helps!
Answer:
Both parents have the genes for yellow peas and green peas
Explanation:
If a plant has inherited one yellow peas gene and one green peas gene, the plant will produce yellow peas because (as you mentioned) yellow peas are dominant. that means the parents are heterozygous (Cc). If both parents have the gene versions Cc, then there is a 25% chance the offspring would get the gene version cc, coding for green peas.
Down syndrome is an example of a condition caused by trisomy<span>. People with Down syndrome typically have three copies of chromosome 21 in each </span>cell<span>, for a total of 47 chromosomes per </span>cell<span>. Monosomy, or the loss of one chromosome in </span>cells<span>, is another kind of aneuploidy</span>
