Multiple Choice

Which chromosomal configuration would be observed in one daughter cell after telophase of mitosis?

A diploid set of chromosomes identical to the parent cell

A diploid set of chromosomes, but with non-identical genetic material due to crossing over

A haploid set of chromosomes with half the number of the parent cell

A tetraploid set of chromosomes with double the number of the parent cell

Verified step by step guidance

Recall the purpose of mitosis: it is a type of cell division that produces two daughter cells genetically identical to the original parent cell, maintaining the same chromosome number.

Understand that during mitosis, the chromosomes are duplicated during the S phase of interphase, so each chromosome consists of two sister chromatids before division.

During telophase of mitosis, the sister chromatids are separated into two daughter nuclei, each receiving one copy of each chromosome, restoring the diploid chromosome number.

Note that crossing over, which results in genetic recombination, occurs only during meiosis (specifically prophase I), not mitosis, so the genetic material in mitotic daughter cells remains identical.

Conclude that each daughter cell after telophase of mitosis contains a diploid set of chromosomes identical to the parent cell, neither haploid nor tetraploid.
