Question

List any two pairs of visible contrasting characters of garden pea plants used by Mendel for his experiments stating the dominant and recessive characters in each pair.

Accepted Answer

## Model Answer **Pair 1: Plant Height** - Dominant character: Tall plant - Recessive character: Short plant **Pair 2: Seed Shape** - Dominant character: Round seeds - Recessive character: Wrinkled seeds *(Any other valid pair such as Flower Colour — Violet (dominant) / White (recessive) is also acceptable.)* Source: Chapter 8, Section 8.2.2 --- ## Explanation - The question asks for **two pairs**, each with the dominant and recessive character clearly named — that's 1 mark per pair. - Mendel's seven pairs include: tall/short, round/wrinkled seeds, violet/white flowers, yellow/green seeds, etc. State any two. - Always write which is dominant and which is recessive explicitly — don't just list them, or you may lose marks.
