Question

12. Study the image of a chromosome. Which of the following statements about

the chromosome is true?*
chromosome
A. Each half of the chromosome is genetically identical.
B. Once formed, a chromosome always stays in this X shape.
C Each half of the chromosome contains genetically different material
D. The pinched middle of the chromosome is what allows it to split during mitosis.

Answer 1

C

Step-by-step explanation:

I would say it is C.

Each cell has 23 chromosome (46 in total). 23 is from our mother, 23 from our father. So this would mean the chromosomes are not genetically identical, hence we have variation.

Hope this helps!

Answer 2

A. Each half of the chromosome is genetically identical.
