Question

Two nucleotide sequences found in two different species are almost exactly the same. This
suggests that these species :
A) contain identical DNA
B) may have similar evolutionary histories
C) have same number of mutations
D) both are evolving into same species​

Answer 1

B is correct answer

Answer 2

Answer:

B) may have similar evolutionary histories

Explanation:

• To determine which organisms in a group are most closely related, molecular features such as nucleotide sequences of genes are studied.

• Biologists often compare the sequences of homologous genes. That depicts,

• If two different species have the same genetic makeup, it means that they received or developed it from a common ancestor. And in the course of evolution, they inherited this similarity from that same ancestral origin.

Hence option B) is correct.
