Answer:
The options have been placed in the comment section. The answer is C. Inheritance of genes from both parents
Explanation:
Gregor Mendel is referred to as the FATHER OF GENETICS due to his immense contribution to the discovery of how traits are passed down or inherited from parents to offsprings. He found out that a unit of inheritance, which was later called GENE, was responsible for each individual trait of pea plants.
In his numerous experiments, Mendel discovered that the characteristics/traits of pea plants were determined by the contribution of both parents. Mendel hypothesized that each parent contributed 50% of this unit of inheritance via fertilization to the characteristics of an offspring. Hence, the inheritance of genes from both parents determines the characteristics of a pea plant.
