Question

What was Mendel's most important contribution to the modern understanding of biology?

• A. The concept that meiosis reduces the chromosome number to half
• B. The concept that chromosomes are present in the nucleus
• C. The concept that genes are ordered along chromosomes
• D. The concept that hereditary information comes in discrete units

Answer 1

The correct option is D

The concept that hereditary information comes in discrete units

Mendel's most important contribution to the modern understanding of biology is that hereditary information comes in discrete units. He deduced from his experiments that each character is controlled by discrete units and they are paired, each one inherited from a parent. He called these units as factors. Now we call them as genes.
