Question

What do you mean by law of segregation.

Hint:

The Law of Segregation is also known as the "Law of Purity of Gametes" because it is a universal law of inheritance with no known exceptions.

Answer 1

Step 1: This law states that during the formation of gametes, the two factors (alleles) of a character separate or segregate from each other.
Step 2: A gamete receives only one of the two factors, ensuring it is always "pure" for a specific trait.
Step 3: This explains why the recessive trait, which remains hidden in the $F_1$ generation, reappears in the $F_2$ generation.
