Helper T cells are found in the <u>Thymus.</u>
Explanation:
Immature T-cells are formed in the bone marrow, just like any other blood cells, through the process of hematopoiesis. These immature T cells are then transported to the thymus where they mature and differentiate into the different types of T cells; cytotoxic, helper and regulatory. T-helper cells, also called CD4⁺ cells, are important in activating B-cells and T-cytotoxic cells in case of infection.

Answer:
Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection)
Inbreeding refers to sexual reproduction between genetically close individuals.
Interbreeding refers to reproduction with another species or race. Interbreeding is basically the same as cross-breeding.
