What would be the main problem with reproduction if meiosis did not take place to form sex cells?

A
The zygote would have two nuclei.
B
Fertilization would result in a zygote with half as many chromosomes as the parents.
C
Fertilization would result in a zygote with twice as many chromosomes as the parents.

Four haploid cells are formed.
B
Two diploid cells are formed.

Anna and Louis are talking about this diagram.

Question illustration
A
Anna is correct because the chromosomes are being pulled apart, which happens in anaphase I.
B
Louis is correct because the chromosomes are being pulled apart in two haploid cells, which indicates anaphase II.
C
They are both correct because the process of anaphase is the same in meiosis I and meiosis II.
D
Neither is correct because the chromosomes are being pulled apart, which happens in metaphase.

Question illustration

Forms diploid cells
B
Creates an even number of cells
C
Includes two rounds of cell division
D
Duplicates body cells

Allison and Greta are discussing mitosis and meiosis. Allison says that body cells such as muscle cells would use mitosis, and Greta says that body cells would use meiosis.Who is correct?

A
Allison, because body cells need to be haploid, genetically different copies, which are produced through mitosis
B
Allison, because body cells need to be diploid, identical copies, which are produced through mitosis
C
Greta, because body cells need to be haploid, identical copies, which are produced through meiosis
D
Greta, because body cells need to be diploid, genetically different copies, which are produced through meiosis
