Question

Why was it important that Mendel chose true-breeding varieties for his experiments?

1) To ensure that the traits being studied were not influenced by other genetic factors
2) To make the experiments easier to conduct
3) To increase the chances of obtaining accurate results
4) To demonstrate the principles of inheritance

Answer 1

Mendel chose true-breeding pea plants to ensure traits were not influenced by other genetic factors, making it easier to observe inheritance patterns and obtain statistically significant results, thereby demonstrating the basic principles of inheritance. The correct option is 1) To ensure that the traits being studied were not influenced by other genetic factors

Step-by-step explanation:

It was important that Gregor Mendel chose true-breeding varieties for his experiments for several reasons. First and foremost, using true-breeding pea plants ensured that the traits being studied were not influenced by other genetic factors, allowing Mendel to accurately determine how traits were passed from one generation to the next.

Moreover, by ensuring that the offspring would resemble their parents, Mendel could make clear, predictable observations about inheritance patterns.

Finally, this approach supported Mendel's ability to conduct large numbers of experiments on different traits within a relatively short time frame, leading to statistically significant results and the establishment of the basic principles of inheritance. The correct option is 1) To ensure that the traits being studied were not influenced by other genetic factors
