Abstract excerpt
The allele frequencies of 2 new polymorphic markers of collagen type I proalpha 1 (COL1A1) and proalpha 2 (COL1A2) genes were determined in a random sample of chromosomes by polymerase chain reaction. The minor allele frequencies were 0.27 for COL1A1/+88Mn1I, and 0.39 for COL1A2/1446 PvuII RFLPs, respectively. These 2 polymorphisms increased the combined (PIC) values we previously determined in the Italian...
