New alleles can be created in all of the following ways, except by a) removing a dna base at a point in the gene. b) the addition or removal of a chromosome by a meiosis error. c) substituting a dna base at a point in the gene, with a different one. d) mixing segments of the same gene, from two parents, during crossing-over in meiosis.

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

raits that your monster will have. the dna code for each trait is given, so you will need to go through the process of transcription and translation to determine what protein is being made and then match that with the corresponding trait. you may even include a picture of your monster if you are feeling creati
