What's the difference between linear and transvection?
Linear
Definition:

(a.) Like a line; narrow; of the same breadth throughout, except at the extremities; as, a linear leaf.

Transvection
Definition:
(n.) The act of conveying or carrying over.
Example Sentences:
(1) Chromosomal rearrangements which disrupt transvection possess a breakpoint in a particular segment of the chromosome arm bearing the transvection-sensitive gene (arm 2L for the DDP-C and 3R for the BX-C); this segment of each arm has been termed the critical region by Lewis (1954).
(2) The zeste gene product is required for transvection effects that imply the ability of regulatory elements on one chromosome to affect the expression of the homologous gene in a somatically paired chromosome.
