The presence of the 60 percent of similar genes in the fruit flies and humans, and 97.5 % similar genes in humans and mice suggests that the common ancestory of the humans and mice is much more recent than the common ancestory of humans and fruit flies. The majority of the similar genes in the mice and humans is the indication that they have evolved from a common ancestor not very long ago. However, only 60% similarity between fruit flies and humans indicates that it had been some time since they both have had a common ancestor.
Hence, the correct answer is 'Option D'.
The full DNA base sequence that determines the placement of each amino acid in a complete protein, a subset of a protein, or any other functional product is referred to as a gene.
<h3>What are Genes?</h3>
The hereditary and functional unit of life is the gene. DNA makes up what they are. It is likewise regarded as the fundamental unit of inheritance. The information required to define physical and genetic makeup is found in the genes, which are handed from parents to offspring. It governs how an organism functions, looks, survives, and interacts with its surroundings. Moreover, Protein-coding genes and noncoding genes are the two categories of genes.
