The following questions refer to the description below. You are taking a group of students on a nature walk around the university campus.Several students come up and show you oak leaves they collected from one tree.The students are confused as to why you they see such variation in leaf size if all the leaves came from one tree and are genetically identical. -Using the example of the oak leaves,what is the best explanation for why a single genotype can produce different phenotypes?
A)The smaller leaves are not fully grown yet, and will keep growing until they reach their full size. B)Shade leaves are large, providing a large surface area for absorption of light, whereas leaves that grow in the sun receive abundant light and have a smaller surface area to decrease water loss. C)The oak tree consists of two genotypes; someone had grafted a branch from another oak tree. D)Smaller leaves may have a mutation that inhibits growth and photosynthesis.
