When is mitosis complete?

B

Explanation:

Mitosis is complete when it has finished its last stage, which is known as telophase. During telophase, the chromosomes or the genetic material are already separated on opposite sides of the large cell. When this happens, the chromosomes begin to be enveloped in their own separate nuclei.

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )
