Using PCR analysis of pig-mink and pig-Chinese hamster hybrid cell lines an
d heterologous and homologous primers of various types, chromosomal and sub
chromosomal mapping of genes TOP2A, THRA, BRCA1, GAS, HLR1, MYL4, LIS1, MCP
1, ENO3, CRYB1, P4HB, STAT5B, and H3F3B to pig chromosome 12 was carried ou
t. The efficiency of using different types of heterologous primers for pig
chromosome mapping was compared.
