Answer:
A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent.
Explanation:
The answer is granzymes. are serine proteases which trigger the apoptotic cascade in target cells. Apoptotic enzymes activated by granzymes can also destroy viruses or other cytoplasmic pathogens in the target cells so that the pathogens cannot infect nearby cells. Dead target cells are rapidly ingested by macrophages. The Tc cells also produce perforin pores to allow granzymes to enter the target cell.
