weak linkage – biological processes can interact without having to know too much about each other ??? this facilitates “evolvability” by reducing constraints, increasing robustness and allowing the accumulation of genetic variation. evolvability may have been selected for during evolution.
The genes which are closely located show strong linkage, whereas those, which are widely separated, have more chance to get separated by crossing over (weak linkage). 4. Linked genes remain in their original combination during course of inheritance.
20 Ιουν 2023 · This phenomenon is called linkage, and is a major exception to Mendel’s Second Law of Independent Assortment. Researchers use linkage to determine the location of genes along chromosomes in a process called genetic mapping and is important to natural processes of heredity and evolution.
We show and explain mathematically that this patterning enhances stability, because it reduces maximum “loop weight” and thus reduces the amount of intraspecific interaction needed for matrix stability. The patterns are brought about by biomass pyramids, a feature common to most ecosystems.
29 Ιουλ 2015 · We show that such “weak on weak” interactions (including weak harvesting) have an inordinate ability to destabilize a food web (sensu Keystone species; we will return to this in the...

Weaker bonds can also form between molecules. Two weak bonds that occur frequently are hydrogen bonds and van der Waals interactions. Without these two types of bonds, life as we know it would not exist.
