Life of the drosophila
Drosophila flies reach a length of 1 to 2 millimetres. Drosophila flies are attracted to fruit, in which they lay their eggs and in which the larvae grow. They multiply very quickly and in a very large numbers.
The most well known Drosophila species is certainly Drosophila melanogaster, which is a model organism for biologists, especially in the genetic sciences. Its genome is entirely sequenced and includes 4 pairs of chromosomes, or 165 million basic pairs.
