Question

if a scientist wanted to follow mendels experiment with a different kind of plant, which type of plant would she examine?
a plant that cannot self - pollinate.
a plant that has only recessive alleles.
a plant that has three alleles for a trait.
a plant that has only two alleles for a trait.

Explanation:

Mendel's genetic experiments relied on plants with clear, binary trait inheritance, governed by two alleles (dominant/recessive) per trait, and the ability to control pollination. Self-pollination was key for his pure-breeding lines, and he studied traits with two distinct allele forms.

• Option 1 is wrong: Mendel used self-pollinating pea plants.
• Option 2 is wrong: He used both dominant and recessive pure lines.
• Option 3 is wrong: His work focused on traits with two alleles, not three.
• Option 4 matches Mendel's core experimental requirements.

Answer:

D. A plant that has only two alleles for a trait.
