You go on a trip to the Galapagos island to study the animals there for a paper you are writing on evolution, just like Darwin did. You spend 3 days taking notes on all the physical characteristics you can observe about the tortoises and then you spend 3 days observing the finches. What have you recorded? A. Inherited characteristics B. Environmental variation factors C. Phenotypes D. Genotypes

Answers

Answer:

C. Phenotypes

Explanation:

Taking notes on all the physical characteristics observed about the tortoises and then observing the finches, I have observed the phenotypes.

Phenotypes are the observable characteristics of a species which are the result of genetic expression influenced by the environmental factors.

So, phenotypes will be recorded during the trip while taking notes on all the physical characteristics which can be directly related to genotype and environmental factors.

Hence, the correct option is "C. phenotypes".

The correct answer is C because the others don’t work
