A snake coming out of its hole in a dream represents a son. A snake leaving one's house in a dream means its destruction or demolition. Killing a snake in a dream means marriage. Tapeworms or other intestinal worms in a dream represent one's relatives and their children.
Single-phasing is a special type of open circuit fault in which only one phase of a three-phase system is disconnected, causing the remaining two phases to form a single-phase system [1]. Single-phasing may happen for a variety of reasons.
Single genes do not always work as simply as indicated by a dominance and recessive relationship. Other genes can affect the phenotypic expression of a given gene. One example is epistasis (standing on) where one locus can mask the expression of another. Classic example is a synthetic pathway of a pigment. Mutations at loci controlling the early steps in the pathway (gene 1) can be epistatic.
