<span>Nails are hard plates of tightly packed keratinized cells. They are clear and cover the dorsal surface of the last phalanges of fingers and toes. Nails protect the the ends of the fingers, allow us to scratch various parts of our body and help us grasping and manipulating small objects.
</span>The site of nail growth is the nail matrix<span> that is found beneath the nail root. The nail matrix is thick and is only composed of the deeper layer of the epidermis: the stratum basale (or germinativum). The keratinization of the cells of the nail matrix proceeds in the absence of a stratum granulosum and lucidum and this results into formation of a of a rigid and durable plate. As the nail matrix thus proliferates and differentiates, this hard plate is pushed forward onto the nail bed and the nail grows.</span>

Recessive traits are only expressed when both the copies of recessive genes are inherited from the parents.
Therefore, recessive traits would never reappear if zygotes were given opposite alleles.
