Worked practice questions

In ASEXUAL reproduction, how many parents are involved?

  1. Two
  2. Zero
  3. One
  4. Three or more
Show answer and solution

Correct answer: C. One

Asexual reproduction involves a single parent only. The offspring are produced from a part of the parent body (or from a single cell) and are genetically (almost) identical to the parent — clones.

In SEXUAL reproduction, the offspring inherit:

  1. Genetic material from neighbours
  2. Genetic material from both parents — leading to genetic variation
  3. Genetic material from one parent only
  4. No genetic material
Show answer and solution

Correct answer: B. Genetic material from both parents — leading to genetic variation

Sexual reproduction combines genetic material (chromosomes) from both parents — male and female gametes fuse to form a zygote. Offspring share characters from both parents, and the recombination creates genetic variation across the population.

A small outgrowth on the parent body that develops into a new individual (seen in Hydra and yeast) is called:

  1. Zygote
  2. Spore
  3. Bud
  4. Seed
Show answer and solution

Correct answer: C. Bud

In budding, a bud develops on the parent body (or in a single cell like yeast). The bud grows, then separates to become an independent organism. Hydra and yeast both reproduce by budding.
