NEET Botany Multiple Alleles MCQ Question
Which of the following statements about multiple alleles is correct?
Multiple alleles can exist in a population, but an individual can carry only two of them.
Multiple alleles allow for blending of traits in the offspring.
All alleles for a given trait are equally dominant when expressed.
A single gene can produce multiple phenotypic effects regardless of the alleles present.
Correct Answer
Detailed Explanation
Statement A is correct as it reflects that multiple alleles exist within a population while individuals only possess two. Statement B is incorrect because multiple alleles do not cause blending; traits can be expressed distinctly. Statement C is false as not all alleles are equally dominant. Statement D misrepresents the relationship between alleles and phenotypic effects, as multiple phenotypic outcomes can arise from different alleles but do not imply multiple alleles are needed.
