Abstract: 
The chromosome is the genetic blueprint for all living things, from plants to animals to even individual cells, and is responsible for passing on traits from parents to offspring. DNA in chromosomes determines how offspring will look.Some insects just deposit their eggs wherever they happen to be, whereas others choose to hide them, such as in tree trunks or dead animal tissues, or even to attach them to the male's posterior after mating. And the eggs of cockroaches and grasshoppers are encased in a spongy material; And just a few of insect species may reproduce without fertilization; in these cases, the females nonetheless reproduce and develop normally despite having only half as many chromosomes as viable eggs. typical of aphids and other small insects that feed on juice. In the spring, when food juice is plentiful, plants produce offspring asexually; in the summer, when food is short, they reproduce sexually. In conclusion, it is safe to assume that most bug species place their eggs in close proximity to a food supply.
