Answer:
Mechanism of population-control of mosquitos
Step-by-step explanation:
The X513A is a genetically engineered mosquito to carry a dominant gene that makes then infertile, affecting population growth and reducing vectors of diseases such as yellow fever and dengue fever. Thanks to this method the mosquito's offspring cannot reproduce as well, and because its gene is dominant it ends up covering the fertile mosquito gene form it's competitors. This technique has been used since the 70s, and has been shown to be effective in disease control.
