Question

When Mendel crossed a pure white flowered strain of pea with a pure red flowered strain, the first generation hybrids had:

विकल्प

• only red flowers

• only white flowers

• pink flowers

• three red and one white flowers

Answer 1

only red flowers

Explanation:

When Mendel crossed a pure white flowered strain of pea with a pure red flowered strain, all the first generation (F₁) hybrids had only red flowers. This happened because the red flower color allele is dominant over the white flower color allele, so the white color trait was suppressed in the F₁ generation. Mendel called the red flower color dominant and the white flower color recessive, demonstrating his Law of Dominance.
