Answer:

Option B, the addition or removal of a chromosome by a meiosis error.

Explanation:

Any change in the total chromosome number in any species lead to development of chromosomal disorder.  

For creating new alleles, it is essential to induce a change in the nucleotide sequence of the DNA of any organism. This is basically done before, after or during the cell division.  

The common methods of changing the nucleotide sequence of DNA is through insertion, deletion, or substitution of nucleotide sequence in any gene sequence.

Hence, option B is correct

Which of the following is the broadest level of classification for living things?
Lunna [17]

The answer is Domain. It is also referred to as Superkingdoms. There are three domains in current classification system namely; Archaea, Bacteria, and Eukarya. The first two classify single-celled organisms whose cells have no nucleus while Eukarya classifies organism that have a nucleus bound by a membrane. The difference between Archaea and Bacteria is their membrane structure; Archaea’s membrane is characterized by membrane lipids that are branched hydrocarbon chains attached to glycerol by ether linkages, while Bacteria’s is made of unbranched fatty acid chains attached to glycerol by ester linkages.
