प्रश्न
Sahil performed an experiment to study the inheritance pattern of genes. He crossed tall pea plants (TT) with short pea plants (tt) and obtained all tall plants in F1 generation.
Give a reason why only tall plants are observed in F1 progeny.
उत्तर
Traits like ‘T’ are called dominant traits, while those that behave like ‘t’ are called recessive traits. Alternatively, accept the definition of dominant and recessive traits with examples of T and t respectively or Alternatively accept the law of Dominance with examples of T and t.
