Question

how are mitosis and meiosis similar?
a. they both increase the chromosome number
b. they both involve duplicating chromosomes
c. they both produce tetrads
d. they both produce gametes

Explanation:

Mitosis and meiosis both start with chromosome - duplication before cell - division. Mitosis is for growth and asexual reproduction, and meiosis is for sexual reproduction. Option A is incorrect as neither increases chromosome number. Only meiosis produces tetrads (during prophase I) and gametes.

Answer:

B. They both involve duplicating chromosomes
