Detailed explanation-1: -Evolutionary descent and gene similarity are relatively connected with each other. If two species have the same DNA sequence in their genes, this indicates that they are sharing a common ancestor. A. Species A and B shared a relatively recent common ancestor.
Detailed explanation-2: -The shared genes are called homologous genes, or genes which share a common ancestry either between or within species.
Detailed explanation-3: -Genes and proteins are similar to homologous structures when determining evolutionary relationships among species . If two different species have similar set of genes or proteins it increases the likelihood of shared ancestor.
Detailed explanation-4: -Terms in this set (8) What is true about similarities to classify different species? Species are not compared for the purpose of classification. If species A and B have very similar genes and proteins, what is probably true? Species A and B shared a relatively recent common ancestor.
Detailed explanation-5: -DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
