Short Answer

Expert verified

Question: In meiosis, the daughter cells have ____________ compared to the number of chromosomes in the parent cell. (a) Half the number of chromosomes (b) Double the number of chromosomes (c) The same number of chromosomes (d) A variable number of chromosomes Answer: (a) Half the number of chromosomes

Step by step solution

Definition of Meiosis

Meiosis is a process of cell division that results in four non-identical daughter cells, each with half the number of chromosomes as the parent cell. This process is important for sexual reproduction, as it creates the gametes (sperm and egg cells) needed for the formation of new offspring.

Comparing Chromosome Numbers

In meiosis, the chromosomes in the parent cell are duplicated during the initial steps of division, followed by two rounds of cell division (meiosis I and meiosis II). The end result is four daughter cells, each with half the number of chromosomes as the parent cell. This ensures that when the gametes combine during fertilization, the resulting offspring will have the correct number of chromosomes.

Selecting the Correct Answer

Based on the definition and understanding of meiosis, we can conclude that the correct answer is: (a) Half the number of chromosomes. Meiosis results in the formation of daughter cells with half the number of chromosomes as the parent cell. This ensures that when gametes combine during fertilization, the offspring will have the correct number of chromosomes.
