Answer: It is because it makes it more efficient to study organisms.
Explanation: Biologist classify organisms by considering similarities between them. The organisms which have closely related characteristics are placed in a separate domains by biologists. Domains are further divided into 6 Kingdoms. According to modern classification system, domain is largest unit of biological classification.
Reproductive isolating mechanisms are barriers which impeded mating (prezygotic) or prevent the hybrid from developing properly (postzygotic) but the overall effect is to cause speciation by making it difficult for two diverging species to share genes. So one kind of mechanical isolation could be the usage of contraceptives. As of temporal isolation, or behavioral isolation could be exemplified by people who suffer from diseases that cause separation (such as HIV or cancer).

Answer:
The correct answer is : the female chromosome
Explanation:
- According to the question, it is mentioned that R is a dominant allele, responsible for the red eyes.
- RR is a genotype for Red eyes.
- A fruitfly has a diploid genotype which means each trait is represented by a pair of chromosomes.
- In the above question, the dominant red eye colour trait is represented by the pair of chromosomes RR.
- Therefore, XX must represent another trait.
- By convention, a pair of X chromosomes (XX) represent a female and a combination of X and Y chromosomes (XY) represents a male.
- Given XX genotype represent a female fruitfly chromosome.
