A cladogram is a type of graph that shows how closely related different types of organisms are in an evolutionary context. It resembles a tree, with various organisms being placed at the end of each branch. If two organisms have a close common branch, they are more closely related than those who have more distant branches. Since DNA, or corresponding protein sequences are more similar in closely related species, and more different in more distant species, a biologist can use those sequences to numerically determine how closely related three species are.

Answer:
The correct answer is option C.
Explanation:
As it is given that, a Mendelian cross is performed between two parents resulted by cross the parents. This suggests that the parents or P generation has zero recombination hence the genotype of Parents would be AA and aa in nature. Therefore, all the F1 generation offspring were Aa in nature. The selfing of the F1 offspring will be:
A a
A AA Aa
a Aa aa
Genotype: AA: Aa: aa :: 1:2:1
Phenotype: Dominant: recessive :: 3:1
