A lod score of 3 or higher is usually considered convincing evidence for linkage.

A lod score of -2 or lower is usually considered convincing evidence for independent assortment.

In proteins, there are three types of chromophores relevant for UV/Vis spectroscopy:

peptide bonds (amide bond);

certain amino acid side chains (mainly tryptophan and tyrosine); and

certain prosthetic groups and coenzymes (e.g. porphyrine groups such as in haem).

(MARs) also called scaffold attachment regions (SARs), or S/MARs in case of metaphase chromosome as the same sequences appear to attach to the protein substructure in both metaphase and interphase cells.

ABa and ABp are equivalent cells whose fates are determined by their positions in the embryo (if one experimentally reverses the positions of these two cells, their fates are similarly reversed and a normal embryo forms)
