A trait may be inherited but may not be expressed?Justify the statement by giving the reason behind the conclusion.
Answers
Answer:
Explanation:
This can be explained as the traits are inherited from both the parents but only one f them is expressed. The trait which is expressed is called dominant trait and the other is called recessive trait.
The law of independent assortment states that the inheritance of one pair of genes is independent of inheritance of another pair. THus both the traits are inherited
An experiment by Mendel:
If we cross pure-bred tall (dominant) pea plant with pure-bred dwarf (recessive) pea plant we will get pea plants of F1generation. If we now self-cross the pea plant of F1 generation, then we obtain pea plants of F2 generation. Dwarf plants are not found in Fi generation but appeared in F2 generation. In the F1 generation, the dominant characteristic is Tall which appeared in F progeny but in F2 generation, presence of two recessive characteristics/ traits, the plants which appeared are dwarf. The ratio of tall plants to dwarf plants in F2 generation is: 3:1 It proved that dwarfness which was lost in F1 generation. reappeared in F2 generation.
