Primers complementry to the chicken middle repetitive sequence element CR1 were used to generate and simultaneously map polymorphic polymerase chain reaction products (CR1-PCR) with various chicken DNAs as templates. Ten primers were prepared using the sequence of a single CR1 element as a guide. These 10 primers generated 23 polymorphic CR1-PCR products. The average number of polymorphic CR1-PCR products generated using single primers(1.1 per primer) was significantly higher than the average number observed using combinations of two primers(0.3 per primer combination). The polymorphic CR1-PCR products were mapped in a subset of a reference backcross population designed for the genetic linkage analysis of the chicken. Nineteen of the polymorphic CR1-PCR products identified were assigned to 13 of 19 linkage groups characterized thus far in this population; three have yet to be linked to a specific map location. One of the CR1-PCR markers mapped to the chicken Z chromosome. There was no evidence for a significant clustering of CR1-PCR markers within the map, even at the site of the CR1 element whose sequence was used for primer design. © 1994 The American Genetic Association.
