Answer: Row X describes meiosis, while row Y describes mitosis.
Explanation: There are two types of cell division: meiosis and mitosis.
In meiosis, a cell divides into twice to produce four identical daughter cells each with half the number of chromosomes in the parent cell.
Therefore, if the parent cell has 14 chromosomes, the daughter cells will have 7 chromosomes.
In mitosis, a cell divides once to produce two identical daughter cells each with the same number of chromosomes as in the parent cell.
Therefore, if the number of chromosomes in the parent cell is 14, the daughter cells will have 14 chromosomes.
