Direction: In the following questions a statement of assertion (A) is...
Assertion (A): Cross of F1 individual with recessive homozygous parent is a test cross.
Reason (R): No recessive individuals are obtained in the monohybrid test cross progeny.
The correct answer is option 'C' - Assertion (A) is true but reason (R) is false.
Explanation:
Test cross:
A test cross is a breeding experiment performed to determine the genotype of an individual. It involves crossing the individual in question with a known homozygous recessive individual. The purpose of the test cross is to determine whether the individual in question is homozygous dominant or heterozygous.
Assertion (A) is true:
When the F1 individual (the offspring of a cross between two individuals that are homozygous for different alleles) is crossed with a recessive homozygous parent, it is called a test cross. This is because the recessive parent will only contribute recessive alleles to the offspring. By observing the phenotype of the offspring, we can determine the genotype of the F1 individual.
Reason (R) is false:
The reason provided states that no recessive individuals are obtained in the monohybrid test cross progeny. However, this statement is incorrect. In a monohybrid test cross, some of the offspring will have the recessive phenotype. This is because if the F1 individual is heterozygous, half of its gametes will carry the recessive allele, resulting in some offspring with the recessive phenotype.
Therefore, the correct answer is option 'C' - Assertion (A) is true but reason (R) is false.
Reason (R): No recessive individuals are obtained in the monohybrid test cross progeny.
The correct answer is option 'C' - Assertion (A) is true but reason (R) is false.
