3. Pleiotropy (or pliotropy) is the phenomenon in which a single gene conditions several different phenotypical traits. Some phenotypical traits may be sensitive to the pleiotropic effects (for example, inhibition) of other genes, even when conditioned by a pair of alleles in simple dominance.A mixture of pleiotropy and gene interaction is characteristic of these cases.1  Non-Mendelian Inheritance-Image Diversity: pleiotropy.ome phenotypical traits may be sensitive to the pleiotropic effects (for example, inhibition) of other genes, even when conditioned by a pair of alleles in simple dominance.

Plagiocephaly (sometimes called deformational plagiocephaly or positional plagiocephaly) is a very common, very treatable disorder. It causes a babyâs head to have a flattened appearance. Plagiocephaly develops when an infantâs soft skull becomes flattened in one area, due to repeated pressure on one part of the head. Many babies develop plagiocephaly by sleeping regularly in one position. This condition occurs more often in premature infants whose skulls are especially pliable.
