Answer:
In case of both DNA and RNA, in general it is the nucleotides.
Nucleotides basically consists of three parts. The sugar(deoxyribose in DNA and ribose in RNA, both of which are pentose sugars), nitrogenous base and a phosphoric acid group.
The only component that varies in the nitrogenous base. There are five different types.
1.Adenine(A)
2.Guanine(G)
3.Cytosine(C)
4.Thymine(T)
5.Uracil(U)
1 and 2 are known as purines.
3, 4 and 5 are known as pyrimidines.
In DNA, A base pairs with T by means of a double hydrogen bond and G pairs with C by means of a triple hydrogen bond.
In RNA, A base pairs with U by means of a double hydrogen bond and G pairs with C by means of a triple hydrogen bond.
Species A and B have fewer differences between DNA sequences means that fewer mutations occurred. It is likely due to sequence homo-logy.
<h3>Whta are mutations?</h3>
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of a particular organism.
The linear order of nucleotides and their differences (mutations) can be used to infer homo-logy between two species.
In this case, there are only two different nucleotides in these sequences, thereby sequence homo-logy indicates a likely common origin.

Answer:
Traits Are Inherited from a Parent through Transmission of DNA. Drosophila chromosome
sorry if this is not the right answer
I think it isn't right to claim that an attribute developed so the species included can survive better, qualities advance since people with that characteristic survive better and duplicate more.
I hope the answer will help you.
