Question

why did mendel choose garden pea plants for his experiments?
they had a limited number of easily observable traits.
they could live in fluctuating laboratory conditions.
they were genetically similar to humans in every aspect.
they were the only available plants he could get in large quantities.

Explanation:

Mendel chose garden pea plants because they had clearly distinguishable traits that were easy to observe and study. This made it possible for him to analyze inheritance patterns. Pea plants also have a relatively short life cycle and are easy to grow and cross - pollinate. The other options are incorrect: pea plants do not live well in fluctuating laboratory conditions (they have specific growth requirements), they are not genetically similar to humans in every aspect (they are plants with a very different genetic makeup from humans), and they were not the only available plants in large quantities (there were other plant species available, but pea plants were ideal for his genetic studies).

Answer:

They had a limited number of easily observable traits.
