Answer:
Species 1(A): D F H I K
Species 2(B): L E
Species 3(C): G J
Explanation: the biological species concept defines a species as a group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring. This means that all members of these populations (called conspecifics) can contribute to a common gene pool. Conspecifics are organisms or populations that belong to the same species. Genes are transferred between conspecific populations through both direct and indirect gene flow.
The genetic variation between humans and orangutans is the greatest is the right option.
Explanation:
A phylogenetic tree is illustration which shows evolutionary relationship between different species. This concept is based on Darwin's descent with modification.
Human and orangutan are 97% similar in their DNA sequences.
The difference in DNA bases shows large genetic variations in both the species.
The species are organized on the basis of traits that are changed over time as compared to their ancestors as they evolve.
Less related species will have more differences in their DNA sequence.
The phylogenetic tree formed indicates that orangutan and human are less related to each other than other species.
