MCQs on Genetic Pattern Of Inheritance Questions and Answers

Genetic Pattern Of Inheritance – Definition


Inheritance pattern is given by Gregor Mendel in the form of Law of Segregation and also by the Law of Independent Assortment. Moreover, there are other genetic pattern of inheritance that can transfer alleles to the member of the population; these includes, Multiple alleles, Incomplete Dominance and Codominance.  All the Genetic Pattern Of Inheritance’s MCQs Questions and Answers are published according to the new study syllabus for the academic year 2021-22.
