Question

why did mendel use cross pollination in his experiments?
peed up self pollination

to make sure dominant
factors were always
produced

to control which plants
pollinated other plants

there werent any bees

to make sure recessive
factors were always
produced

Explanation:

Mendel's experiments with pea plants involved studying inheritance. Cross - pollination allowed him to control which plants were pollinating others. This way, he could carefully select the parent plants with specific traits (like tall or short, purple or white flowers) and study how those traits were passed on to the offspring. The option "to speed up self - pollination" is incorrect because cross - pollination is different from self - pollination. The options about ensuring only dominant or only recessive factors were produced are also incorrect as Mendel's goal was to study the inheritance of both dominant and recessive traits, not to ensure only one type was produced. The option about there not being any bees is irrelevant as Mendel was controlling pollination himself for scientific study, not relying on bees.

Answer:

The option "to control which plants pollinated other plants" (the third option among the visible options in the image, the one with the text "to control which plants pollinated other plants")
