Question

and chromosome number, four daughter cells are produced with half the chromosome number. in fertilization, there is a new genetic combination and the chromosome number is restored. compare the two processes: mitosis and meiosis. can you identify the true statements about
a meiosis results in four haploid daughter cells.
b mitosis results in four diploid daughter cells.
c in both processes, dna replication must occur.
d during meiosis the 2n mother cells produces n daughter cells.
e mitosis is responsible for genetic continuity; in higher organisms it is essential for growth.
f in plants, egg and sperm are produced via mitosis.

Explanation:

• A: Meiosis has two - division cycles and results in four haploid daughter cells, so this is correct.
• B: Mitosis results in two diploid daughter cells, not four, so this is incorrect.
• C: Both mitosis and meiosis require DNA replication before the cell - division process starts, so this is correct.
• D: During meiosis, a 2N (diploid) mother cell produces four N (haploid) daughter cells, so this is correct.
• E: Mitosis produces genetically identical cells, ensuring genetic continuity and is essential for growth and repair in higher organisms, so this is correct.
• F: In plants, egg and sperm are produced via meiosis, not mitosis, so this is incorrect.

Answer:

A. Meiosis results in four haploid daughter cells.
C. In both processes, DNA replication must occur.
D. During meiosis the 2N mother cells produces N daughter cells.
E. Mitosis is responsible for genetic continuity; in higher organisms it is essential for growth.
