Drosophila melanogaster Chromosome Count
Drosophila melanogaster, commonly known as the fruit fly, is an important model organism used in genetics research. It has a diploid chromosome number of 8, which means it has 8 chromosomes in each somatic cell.
Autosomes and Sex Chromosomes
Autosomes are the non-sex chromosomes, and they are present in pairs in both males and females. In contrast, sex chromosomes determine the sex of an individual and are found in one pair in males (XY) and two pairs in females (XX).
Therefore, the chromosome count in Drosophila melanogaster is:
- 3 pairs of autosomes (6 chromosomes)
- 1 pair of sex chromosomes (2 chromosomes)
Hence, the correct option is D) 3 pairs of autosomes and 1 pair of sex chromosomes.
