The most important lesson to be gained from an intensive study of the Cepaea polymorphism is that many types of evolutionary force act upon it and that their relative importance varies between different polymorphic loci, or even when the same locus is studied in different populations. It is ...

Learn about polymorphism, a key concept in object-oriented programming languages like C#, which describes the relationship between base and derived classes.

both sequences of the same accession always appeared together except forH. villosum1029 andH. lucidumwhere they differed slightly in their placement (not shown). As these were minor effects and because of the higher information content of the dominant sequence types in both cases, for the final...
Ten major SGPs and 16 types of patterns were present in 66 cultivated naked varieties, indicating SGPs in cultivated naked barley from Qinghai-Tibet Plateau in China are polymorphic. SGPs in Tibet and Sichuan naked barley were greatly different and SGPs were specific to origin of site. ...

Examples where both types of color polymorphism (conformational and packing) are observed, such as inN-(4-methyl-2-nitrophenyl)acetamide, dimethyl 2,5-dichloro-3,6-dihydroxyterephthalate, and ROY, have also been discussed, revealing the interplay between the two factors in determining the considered...
Restriction fragment length polymorphism (RFLP) analyses of industrial Saccharomyces yeast DNA have identified eight 2-m plasmidsvariants that fall into two distinct types. Type-I plasmids are of unique form, whereas type-II plasmids exist in seven distinct RFLP forms. Only two different 2-m varian...
We have examined leukocyte DNAs obtained from 21 patients with various types of leukemia for the Sacl polymorphism of H‐ras‐1. The patients included ten with B‐lineage leukemia, two with T‐cell leukemia, and nine with acute myelogenous leukemia. Using a genomic probe for H‐ras‐1 in ...
