Mendel studied inheritance of seven pairs of traits in Pea which can have 21 possible combinations. If you are told that in one of these combinations, independent assortment is not observed in later studies, your reaction will be:
Correct answer: B. Mendel might not have studied all the combinations
- A. Independent assortment principle may be wrong
- B. Mendel might not have studied all the combinations
- C. It is impossible
- D. Later studies may be wrong.
Explanation
Law of independent assortment states that when two individuals differ from each other in two or more pairs of factors, the inheritance of one pair is quite independent of the inheritance of other. Law of independent assortment is applicable to only those factors or genes which are located on different chromosomes.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
