Question

in the diagram, n represents the number of chromosomes in the cell. what is happening in the diagram? the 2n cell is producing four 1n gametes by meiosis. the 2n cell is producing four 1n offspring through asexual reproduction. the 2n cell is producing four 1n gametes by the process of fertilization. the 2n cell is producing four 1n cells by going through mitosis.

Explanation:

• Meiosis: A type of cell division that reduces the chromosome number by half, producing four haploid (\(1n\)) gametes from a diploid (\(2n\)) cell.
• Asexual reproduction: Usually involves mitosis (cell division resulting in two daughter cells with the same chromosome number as the parent cell, \(2n

ightarrow2n\)), not reducing chromosome number to \(1n\) for offspring.

• Fertilization: Is the process of combining gametes (not a process of producing gametes). It results in a diploid zygote (\(1n + 1n=2n\)).
• Mitosis: Produces two daughter cells with the same chromosome number as the parent cell (\(2n

ightarrow2n\)), not four \(1n\) cells.

Answer:

The \(2n\) cell is producing four \(1n\) gametes by meiosis.
