Asingle flowering plant produces pollen with a mutation that causes the pollen tubes to grow to only half their normal length. what will be the most likely long-term effect of this mutation on the local population of this type of plant? (2 points) the pollen tubes will reach the eggs sooner, which will result in seeds from this pollen being produced faster, making the mutation more likely to get passed on. since the pollen tubes cannot grow long enough to reach the eggs, the mutation will not be passed on and will not affect the plant population. plants produced from eggs fertilized by this pollen will only grow half as tall as the others, resulting in a population with short and tall plants. within a few generations the mutation will have spread through the population, making all the pollen tubes shorter.

Since the pollen tubes cannot grow long enough to reach the eggs, the mutation will not be passed on and will not affect the plant population.

Explanation:

Took the test and got it right.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
