Question

Assertion: In multiple alleles, many alleles are present in a population for a character.
Reason: All these alleles are present in an individual.

• A. Both assertion and reason are false
• B. Both assertion and reason are true and the reason is a correct explanation of the assertion
• C. Assertion is true but the reason is false
• D. Both assertion and reason are true but the reason is not a correct explanation of the assertion

Answer 1

The correct option is C Assertion is true but the reason is false

The assertion is true; in a multiple allele system, many alleles are present in a population for a character but the reason is false because an individual contains only two alleles. The best example of multiple alleles is the ABO blood grouping system.
Within the population, possible combinations are $I^A{I}^A/I^A{I}^O,I^B{I}^O/I^B{I}^B,I^A{I}^B,I^O{I}^O$, but in an individual only one condition of the above combinations is possible.
