Unlocking the Secrets of Genetics with Gregor Mendel

What are Gregor Mendel's significant contributions to science?

A. Mendel formulated a hypothesis and then tested it.

B. Mendel coined the word genes to describe inherited traits.

C. Mendel studied the pea plants he grew in his garden.

D. Mendel found evidence that there are two factors for each trait.

Answer:

The correct answer is option D: Mendel found evidence that there are two factors for each trait.

Gregor Mendel, often referred to as the father of genetics, made groundbreaking contributions to the field of science through his experiments with pea plants. By meticulously studying the traits of pea plants in his garden, Mendel discovered evidence that there are two factors responsible for carrying traits from one generation to another.

These factors manifested as dominant traits, which were visible in the first generation (F1), and recessive traits, which became apparent in the second generation (F2). For example, the shape of pea seeds could be either round (dominant) or wrinkled (recessive).

Through his work, Mendel formulated essential laws of genetics that laid the foundation for our understanding of inheritance. His findings revolutionized the field of genetics and provided a framework for future scientific discoveries.
