Question

happen? this very question was the center of mendel’s experiment. he needed to find out if the white-flower trait really “disappeared” or if it was somehow still present in the purple-flowered offspring (f₁). to find out, you will need to cross two of the offspring together. is this a case of inbreeding? yes. (calm down, they’re plants, they do that.) if they produce white flowers, you’ll know that the trait is still present inside them.

what is the purpose of self-fertilizing one of the offspring of your first cross?

• to grow more purple flowers
• to see if the f1 flowers can reproduce
• to determine if the white-flower trait may be present but \hidden\ in the f1 flowers
• to show that the purple trait disappeared in the f1 generation

Explanation:

The question is about Mendelian genetics (a topic in Biology, part of Natural Science). Self - fertilizing F1 offspring (purple - flowered, from a cross likely involving white and purple flower traits) is done to check if the white - flower trait, which seemed to disappear in F1, is actually present (recessive) and can reappear in F2. The first option is incorrect as the goal isn't just more purple flowers. The second option is wrong as it's not about F1's ability to reproduce but about trait presence. The fourth option is incorrect as the experiment is to see if the white trait is hidden, not that purple disappeared. The third option matches the purpose of checking for a hidden (recessive) white - flower trait in F1.

Answer:

To determine if the white - flower trait may be present but "hidden" in the F1 flowers
