Answer:
Inheritance of genes from both the parents determine the characteristic of pea plant in Mendel's experiment.
Explanation:
Mendel from his experiments postulated that genes are in the form of pair of alleles. They can be dominant or recessive in their occurrence. Depending upon the traits appeared in the pea plant he gave three laws:
Law of Dominance
Law of Segregation
Law of Independent Assortment
Although both parents will pass on the combination of genes to the offspring only one gene will dominate and appear in the offspring is the law of Dominance.
