Because they were passed down from a common ancestor, homologous structures are those found in related organisms that are comparable. These structures might or might not serve the same purpose in their offspring. The hands of various different mammals are depicted in the figure below. The basic skeletal structure of each is the same.
What is offsrping?
a person, animal, or plant's offspring or progeny is the result of reproduction. Parental transmission of the illness can affect children, a human or animal's direct offspring; a person born of parents gave birth to a lone child.
Creating offspring is considered reproduction. Reproduction comes in two basic forms: sexual reproduction and asexual reproduction. A sexually reproducing creature integrates the genetic material of both parents to create a genetically distinct individual. Asexual reproduction involves the self-replication of one parent to create genetically identical kids.

Answer:
Attached R side groups
Explanation:
The proteins are one of the important biomolecules which are directly coded by the genetic material of an organism.
The proteins are composed of the amino acids which possess, an amine group, a carboxylic group and an attached side group called the R group.
It is the R group of an amino acid which determines whether the amino acid will a polar or a non-polar amino acid molecule thus it determines the properties of the amino acid in terms of chemical properties. The R side group are involved in the formation of bonds with the substrate of the environment and the tertiary structure of the proteins.
Thus, the presence of different R group is the key difference in 20 amino acids.
