NEET Biology: Principles of Inheritance questions with solutions

Q1. Mendel was lucky in the choice of the material of his experiments, which of the following contributed to his success?

1. He observed distinct inherited traits
2. He qualitatively analysed his date.
3. He liked pea plants
4. He considered only one character at one time.

Answer: He considered only one character at one time.

Mendel’s success came from studying one character at a time, which allowed him to follow inheritance patterns without interference from other variables. This made it possible to identify clear ratios and laws of inheritance.
