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.

I was thinking it was B. The plants would not pollinate from the pollinators, then they would not cross-pollinate: not cross-fertilize as often.

Also...

A small creek runs through a mature forest, keeping the soil around the creek damp all year. A variety of ferns and several flowering plants thrive in this shady, moist area. Along the higher ground above the creek, many species of flowering plants that need less water grow. If a farmer diverted the creek to water his fields, causing the creek to dry up, what would be the most likely long-term consequence for the ferns and angiosperms in the forest?  

A. The angiosperms and the ferns would not be affected since their thick, waxy cuticle coverings would protect them from drying out.

B. The angiosperms would outcompete the ferns since their sperm do not need moist conditions to get to their eggs as ferns do.

C. The ferns and angiosperms would begin to produce spores instead of seeds since the spores are better able to survive dry conditions.

D. The ferns would outcompete the angiosperms in the forest since they can tolerate a wider range of moisture conditions than angiosperms.

I was thinking that this was B. also. The ferns have spore in their production, but angiosperms do not. Ferns do not have that waxy coating, as Angiosperms do, so Angiosperms would have a more chance of surviving this drought. The ferns would most defiantly not service a drought, as they need a moist environment to survive..

Thoughts?

Let's take out the answers and see what one is left shall we?

Ok, A.. The offspring would lose its flowers and die from a lack of pollinators. 

No, the plant would not lose is flowers and die from a lack of pollinators. So A. is out.

C. The offspring would produce seeds by asexual reproduction.

The parent rose and offspring have to be genetically identical (have the same genetic content ) to produce seeds by asexual reproduction.
. So C is out.

D. The offspring would yield more fruit than the parent rose. 

The offspring is smaller than the parent rose so it would probably hold less than it. So D is out.

That leaves you with B.!

B. The offspring would not cross-fertilize often with other roses.

 Awesome!

I like how you explained and decided to take which ones do not make since, out of the way...

I like to do the same thing...

B. most defiantly seems like a possible effect of this! n_n

Thank you!
