Question

What is Mendel's first law?

Answer 1

Mendel's law:

1. Gregor Mendel conducted several experiments on pea plants for seven years and then postulated the laws of inheritance.
2. Mendel's law of inheritance includes the law of dominance, the law of segregation, and the law of independent assortment.

Mendel's first law:

1. The first law of inheritance is the law of dominance.
2. The law states that hybrid offspring will only inherit the dominant characteristics in the phenotype.
3. The alleles that suppress a trait are recessive traits, whereas the alleles that define a trait are known as dominant traits.
4. Monohybrid cross helped in proposing the law of dominance.
5. In a monohybrid cross, Mendel crossed two pure pea plants with opposing traits (one short and one tall).
6. Mendel named those first-generation offsprings as F₁ progeny and all the offspring produced by crossing tall plants (dominant trait) and dwarf plants (recessive trait) were tall ( heterozygous dominant or hybrid).
7. After that, Mendel crossed F₁ progeny, and both tall and dwarf plants were obtained in the F₂ generation.
