Answer:
you expect to see that 75% of your F2 generation rabbits have floppy ears and 25% of your rabbits have black fur.
Explanation:
<u> Available data:</u>
- Two true-breeding groups of rabbits.
- The first group has floppy ears and white fur.
- The second group has straight ears and black fur.
- 100% of the F1 generation has floppy ears and gray fur.
- Each of these traits is determined by a single gene and undergo independent assortment.
Having this information we can infer that floppy years, expressed by F allele, might be dominant over straight ears, expressed by f allele. And that the fur color is affected by incomplete dominance, being B the allele expressing black color, b the allele expressing white color and Bb the genotype for grey color.
Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one.

Well for one thing water wouldn't collect in drops. It also would affect pretty much everything that lives in or on water. For example there are kinds of bugs that use the surface of the water to stand on and lots of other organisms that use surface tension for their own benefits. Hope this helps!
