Mitochondrial DNA is a useful marker in phylogenetic studies and molecular systematics because of its maternal inheritance, haploid nature, and rapid rate of evolution (38). Resting, or diapause, eggs are haploid eggs that require fertilization and typically are produced after the production of males by females who have entered the sexual reproductive cycle. Among many ants, bees, wasps, mites, and thrips, for example, unfertilized eggs develop into haploid males, which have just one set of chromosomes. |
