II. An original population of finches on Daphne Island is polymorphic when it comes to beak sizes. (this population feeds on seeds of varying sizes from different species of plants). At first the beak size variations and their main food source were as follows: Small beak/small seeds 25% Medium beak/medium seeds 50% Large beak / large 25%

Hi I need the answer to this question please Thank you

III. An original population of finches on Daphne Island is polymorphic when it comes to beak sizes. (this population feeds on seeds of varying sizes from different species of plants). At first the beak size variations and their main food source were as follows: Small beak/small seeds 25% Medium beak/medium seeds 50% Large beak / large 25% a. Draw a graph of the original population and their beak size/percentage. (Assume this is the original population with plenty of food sources for each). b. A 10-year drought hit the island which kills the plants that produce both the small seeds and the medium size seeds. Describe the allele frequency shift and draw a graph to show the difference in the beak sizes at the end of the ten years. Draw a graph representing your hypothesis. c. What type of selection would this be?
