Answer to Question #214549 in Genetics for moe

Question

2.6) What chromosomal phenomenon lessens the co-migration of loci located on the same chromosome and what is the significance of this phenomenon?

Answer 1

Incomplete linkage occurs when two loci are located on the same chromosome but the loci are far enough apart so that crossovers occur between them during some, but not all, meioses. Genes that are on the same chromosome are said to be syntenic regardless of whether they are completely or incompletely linked.
