Which of the following best describes what would happen if the offspring of a fragrant, red rose bush produced flowers with no scent and small, pale petals?

a. the offspring would lose its flowers and die from a lack of pollinators.
b. the offspring would not cross-fertilize often with other roses.
c. the offspring would produce seeds by asexual reproduction.
d. the offspring would yield more fruit than the parent rose.

The answer is B. The offspring would not cross-fertilize often with other roses.

Scent and colour of the flowers are important for pollination because they will attract pollinators. Flowers with no scent and small, pale petals will attract much fewer pollinators than flowers with scent and large coloured petals. This means those bushes would not cross-fertilize often with other roses.
However, they would not die from a lack of pollinators, nor would produce seeds by asexual reproduction. Also, they would not yield more fruit than the parent rose, their fruit would probably be very small,
