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.

Blood vessels, which lead to the skin capillaries, become narrower they constrict which allows less blood to flow through the skin and conserve the core body temperature. This is called vasoconstriction.

Infertility is the incapacity to conceive an offspring while erectile dysfunction is the incapacity to get aroused so as to engage in sexual intercourse (mostly in men).
Erectile dysfunction could be caused by stress, cardiovascular diseases, and diabetes. Therefore treating it requires maintaining a healthy lifestyle of nutrition and exercise.
Infertility can be caused by disorders of reproductive organs such as endometriosis and occlusion in the tubes. This can be treated by assisted reproduction (IVF), corrective surgery and education.
