Answer:
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
Step-by-step explanation:
Mutations are the random changes in the genome of organisms. Mutations in germ cells can pass from one generation to next through the process of fertilization and embryo formation. The mutation that renders the pollen tube shorter would not allow the male gametes to reach the egg cell to produce the zygote. Since the given mutation prevents fertilization, it will not be passed to the next generation.
