in a population of a plant species, 225 plants are tall, while 26 are short. the height of the plant is controlled by a single gene, and only two alleles are present in this population: t (tall) and t (short), with t being recessive to t. the table below shows the number of short and tall plants over the next several generations:

generation_tall plants (t)_short plants (t)






1. using the hardy-weinberg equation, is evolution occurring in this population? explain your answer.
2. describe how an increase in competition for sunlight would affect the frequency of t and t over time.
