Answer #1

Answere : If two animals have very similar genetic sequences they are closely related animals.

Explanation : Organisms that share similar physical features and genetic sequences tend to be more closely related. There should be gradual differences in the DNA sequence as organisms become more distantly related.
Closely related organisms should have more similar DNA sequence.

When one species gives rise to another species during evolution, the DNA of the new species will initially be very similar to that of the species that gave rise to it. Due to mutations, the sequences of nucleotide bases in the new species will change. Over time, the new species will accumulate more differences in its DNA. Species that are more closely related therefore have more similarities in their DNA.

  Most people seem to accept that genetic analysis can show us how closely related two people are, such as for paternity testing, but some have a more difficult time accepting that genetics shows us how closely related to other animals we are, and even to plants and all other life.

Imagine that you have the DNA sequences from the intron of a gene in three species called A, B, and C. Species A and B are most closely related, while C is more distantly related. The sequences of A and B differ by 18 base pairs, A and C differ by 26 base pairs, and B and C differ by 28 base pairs. Fossils show that species A and B diverged about 1.2 Mya, but there is no fossil evidence...
