In a sexually reproducing organism, which one of the following statements is appropriate both for the parent and offspring?

Options

  1. AChromosome number increases but DNA content remains constant
  2. BBoth chromosome number and DNA content remains constant
  3. CChromosome number decreases but DNA content remains constant
  4. DBoth chromosome number and DNA content decreases

Correct answer

B. Both chromosome number and DNA content remains constant

Step-by-step solution

Both chromosome number and DNA content remain constant, fertilization and replication process ensure the same number of chromosome and DNA content respectively.
