Question

Name and draw a picture to describe these different types of mutations/chromosomal rearrangements. Assume this is happening in a haploid organism with 3 unique chromosomes.

a.) The number of all chromosomes increases by one.

b.) A mutation decreases the amount of genetic material for a portion of one chromosome.

c.) Two different chromosomes fuse to form one new chromosome.

d.) A mutation removes a copy of a single chromosome.

e.) Which of the above events is likely to have the most negative consequences for the organism & why?

I'm pretty sure a.) is aneuploidy, b.) is deletion, and c.) is translocation but please check me and provide pictures if possible.

Answer 1

I think first would be polyploidy. Because the question is saying number of 'all' chromosomes. I have drawn both the cases, aneuploidy and polyploidy.

Please rate high.
