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

Explain the difference between a monohybrid cross and a dihybrid cross, and give an example of each.
Kay [80]
Monohybrid crosses only look at one genotype. Whereas dihybrid crosses look at two genotypes.
An example of a monohybrid cross would be AA x aa, where A represents the dominant allele, and its phenotype is the colour red, and a represents the recessive allele, and its phenotype is the colour white. 
An example of a dihybrid cross would be SSYY x SsYy, where the letter S represents the size, dominant phenotype is large, recessive is small, and Y represents the colour, dominant phenotype is yellow, recessive is green.
