Mendel's Law Of Independent Assortment MCQs

Mendel’s Law Of Independent Assortment – Definition


Mendel’s Law of Independent Assortment states that “When alleles of more than one trait are followed together in the cross, the alleles of these traits assort independently to each other during gamete formation”. Here we discuss the complete detail of the law of Independent Assortment by Gregor Mendel in the form of MCQs. All the Mendel’s Law Of Independent Assortment MCQs Questions and Answers are published according to the new study syllabus for the academic year 2021-22.

  4. none

Answer: b
