Mendel's Law of Dominance

Mendel’s Law of Dominance

Gregor Mendel, the father of genetics, formulated the Law of Dominance through his experiments with pea plants. The alleles for plant height in pea plants are T (tall), which is dominant, while the t (short) is recessive. When a pea plant has the genotype TT (homozygous dominant) or Tt (heterozygo...

Why do some traits vanish in one generation but reappear in the next?

Mendel bred tall and short pea plants to understand how traits are inherited. The resulting offspring were all tall, forming the first filial or F₁ generation.

He observed that traits like short stem height disappeared in the F₁ generation.
