Exotic insects in Okinawa. Offspring borne by each female were counted every day until the female stopped parturition. Six haplotypes were found based on the mitochondrial CO1 sequences bp. This includes crossing over when two chromosomes align near each other and swap segments of DNA.

Scale insects are plant sap feeders closely related to aphids and whiteflies and are characterized by their unusual shapes.

On the right we have sexual reproduction where in order to produce a new organism, an egg cell and a sperm cell need to get together. 5) Vegetative Propagation. Plants reproduce asexually through their vegetative parts such as leaves, roots, stem, and is known as vegetative propagation. For example, onion bulbs, tubers of potato, runners/stolon, etc. Vegetative propagation is much faster than the sexual reproduction in plants.
