Question

The law of purity of gametes is also called:

• A. Law of dominance
• B. Law of segregation
• C. Inheritance of characters
• D. Both b and c

Answer 1

The correct option is B Law of segregation

Law of dominance states that characters are controlled by discrete units called factors, which exist in pairs. One of the members of the pair, also called an allele, is dominant over the other.

Alleles are alternative forms of the gene. The genes are the units of heredity. The inheritance ensures the transmission of traits from parents to offspring.

During the process of gametogenesis, two alleles for a particular character get separated or segregated such that each gamete receives one allele for each character.

This segregation ensures that the gametes are pure in their trait and that there is no intermixing or blending of traits. Since both the characters get expressed in the $F_2$ generation, hence, it can be concluded that alleles get segregated independently.
