When choosing a model organism, one of the main factors to consider is the complexity of the genome. How many genes does it have? How many non-coding vs. protein-coding sequences? How many chromosomes? Four chromosomes Drosophila melanogaster has four chromosomes, or more precisely, four pairs of chromosomes in each somatic cell: a pair of sex… Continue reading All about Drosophila melanogaster chromosomes

The Drosophila melanogaster life cycle
Drosophila melanogaster (D. melanogaster, or the vinegar fly) is an excellent model organism for many reasons: it has a fully sequenced, well characterized genome; it is capable of learning and other complex behaviors; but perhaps most of all, it has a rapid life cycle. At a temperature of 25°C (that’s ~77 degrees Fahrenheit for those… Continue reading The Drosophila melanogaster life cycle
