Ascientist finds two similar flies that have the same size, coloration, and overall morphology. however, further studies show that no mating is possible between them. what could be the appropriate interpretation for this?
a: both flies belong to the same species but different genus.
b: both flies belong to the same genus but different species.
c: both flies belong to the same genus and same species.

The correct answer to explain the phenomenom in which  two similar flies that have the same size, coloration, and overall morphology. However, further studies show that no mating is possible between them. Is:

B: Both flies belong to the same genus but different species.

Explanation:

The biological definition of species is characterized by the ability of mating and producing fertile offspring. In this case, the organisms can't mate, therefore they don't belong to the same species. Their similarities are due to the "genus" which is a common trait, characteristic, or factor that both share. This can be practically anything, the important thing is that they share it but can't mate to produce offspring.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
