Respuesta: enfermedad de célula falciforme
Explicación: Para algunas condiciones, tener una copia mutada de un gen en cada célula es ventajoso, mientras que tener dos copias mutadas causa la enfermedad. El ejemplo mejor estudiado de este fenómeno es la enfermedad de células falciformes: tener dos copias mutadas del gen HBB en cada célula da como resultado la enfermedad, pero tener solo una copia proporciona cierta resistencia a la malaria. Esta resistencia a la enfermedad ayuda a explicar por qué las mutaciones que causan la enfermedad de células falciformes todavía se encuentran en muchas poblaciones, especialmente en áreas donde prevalece la malaria.

Answer: DNA was the first genetic material.
Explanation:
The genetic code is essentially the same in all the organism. This states that the similar organism can have similar genes in them that codes for the similar proteins hence, called as similar organism.
The genetic material is chemically made of nucleotide which is either being synthesized in the body or being obtained from the environment similar to that of amino acids.
If the genetic code is same one organism descend from the other organism.But these statement does not supports that DNA was the first genetic material to found in living beings.
