The genes are what you look like, hair color, eye color, everything that you can get from your parents. Even if you have a twin, it’s not necessary that you two would have the same genes. For example, one could have green eyes and the other could have brown eyes.

Which of the following is a limitation of the phylogenetic species concept?
dimaraw [331]

Answer:

The limitation of phylogenetic species concept is b. Evolutionary histories are not known for all species.

The phylogenetic species concept shows a unique evolutionary history of one organism with another of the same group. The major set back in the phylogenetic species concept is the lack of evolutionary histories for certain species. So, these organisms cannot be grouped according to the phylogenetic species concept.
