Heredity and Ev...

The phenomenon where individuals of a species exhibit differences in characteristics are called:

A pea plant with yellow and round seeds is crossed with another pea plant with green and wrinkled seeds that produced 49 yellow round and 49 yellow wrinkled seeded pea plants. The genotype of parent plant with yellow round seeds must be:

A pure dominant pea plant producing round yellow seeds is crossed with pure recessive pea plant producing wrinkled green seeds. The number of plants bearing round green seeds in the $$F_1$$ generation of Mendel's experiment is:

Among the following which is not one of the direct conclusion that can be drawn from Mendel's experiment?

The two versions of a trait (character) which are brought in by the male and female gametes are situated on

How are variations created?

Inheritance from the previous generation provides

The long-term consequence of the accumulation of variations is

Fill in the blank:

The sequence of gradual changes which takes place in the primitive organisms over millions of years in which new species are produced is known as
