there is little cross talk between haemoglobin genes

An example of the use a technical term (cross talk) which may be perceived as a simile by a novice or non-specialist:

"Although the process of hemoglobin biosynthesis is exquisitely and tightly regulated, there is little or no direct "cross talk" between the α-like and β-like gene clusters. The fact that equal amounts of α and β globin are produced is the result of intrinsic structural features of the genes and their mRNA products."
