You can use a chromosomal karyotype to see if there are any abnormalities with the normal 23 pairs of chromosomes that every healthy human has. Different abnormalities like an extra chromosome (trisomy), missing a chromosome (Minos omg), or having certain parts missing or added on can lead to a person to be diagnosed with certain disease (ex: Down syndrome is an extra chromosome on the 21st chromosome).

Foodborne illnesses caused by parasites can be best prevented by sanitizing all food contact surfaces after prepping "tcs?" food.
Answer:
one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
Explanation:
Answer:
1. The bacterium Vibrio cholerae obtains genes from its prey, a genetic transfer that occurs through the mechanism of transformation (option d).
2. In the V. cholerae bacterium, the acquisition of new genetic material involves the production of temporary merodiploid cells between the time the genetic material enters the cell and the time when recombination occurs (option a).
Explanation:
1. In pathogenic bacteria such as Vibrio cholerae the introduction of genetic material into their genome produces structural and functional changes that promote their ability to cause disease.
In this case, the incorporation of genes by transformation leads to morphological change, development of colonization factors and strengthening of the toxin that V. cholerae produces.
2. Bacteria are prokaryotic cells whose chromosome charge is haploid, with the ability to have a single allele in the gene that determines a trait, and not in allele pairs, as is the case in eukaryotic cells.
The addition of external genetic material results in the bacterium having two alleles for a gene at any given time, which is called a partial diploid or merodiploid cell.
<u>Once V. cholerae acquires new genetic material it becomes a merodiploid cell while genetic recombination occurs</u>.
