Sea urchin actin gene linkages determined by genetic segregation.
???displayArticle.abstract???
Genetic linkage between the actin genes of Strongylocentrotus purpuratus was investigated by observing the segregation of restriction fragment length polymorphisms (RFLPs). Specific RFLPs of actin gene pairs CyI/CyIIa and CyIIIa/CyIIIb always cosegregated, confirming the linkage groups CyI-CyIIa-CyIIb previously previously determined by molecular cloning. In contrast, RFLPs of actin genes CyI/CyIIa, CyIIIa/CyIIIb, and M all segregated at random with respect to one another. This demonstrates that the known actin gene clusters CyI-CyIIa-CyIIb, CyIIIa-CyIIIb, and the M actin gene are not closely linked.
