I think that this question was asked by a bot made by brainly.
A. cloning
The rest relate to the change or identification of genes.
Answer:
C. Gene trees are only useful studying the relationships of sequences from different species.
Explanation:
Gene tree traces the evolutionary history of a particular gene. It includes all the events like duplication and speciation. It helps to study the relationship of genes from different species. Often these are orthologous genes which came form the same ancestor and code for the same protein indifferent species. Gene tree also helps to study the relationship of genes in the same species. Often these are paralogous genes which evolved by duplication and code for similar but not identical proteins in the same species. Hence, the statement that gene trees are only useful for studying the relationships of sequences from different species is incorrect.
The best choice is Vascular and Dermal
Advantage:
Result in variation among species
Disadvantage:
Slow process
