Question 13

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.

-Using the example of the oak leaves, what is the best explanation for why a single genotype can produce different phenotypes?

Accepted Answer

A) The smaller leaves are not fully grown yet, and will keep growing until they reach their full size.

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.
