乐都山羊红细胞钾型的研究

Investigation on Potassium Phenotypes of Erythrocytes in Ledu Goats

采用火焰光度法对７５只乐都山羊的红细胞钾型进行了调查研究。结果发现：①按红细胞钾浓度，乐都山羊有高钾和低钾两种表型，以高钾为优势表型（８８％）；②高钾型山羊的红细胞钾浓度在４３．５９～８１．３０ｍｍｏｌ／Ｌ之间，低钾型的在９．３７～２１．２１ｍｍｏｌ／Ｌ之间；③Ｋ￣ｈ和Ｋ￣Ｌ等位基因频率分别为０．９３８７和０．０６１９，基因杂合度为０．１１６１。

Seventy five Ledu goats were used to inves hgate the potassium phenotypes oferythrocytes by means of a flame photometry. The results were as follows:(1)There wereboth HK and LK phenotypes in the Ledu goats on the basis of the potassium concentration oferythrocytes and the HK phenotype was a preponderant phenotype (88%).(2)The erythro-cyte potassium concentration in the goats with HK phenotype ranged from 43. 59m mol/L to81. 30 m mol/L,and that with LK phenotype from 9.37m mol/L to 21. 21 m mol/L.(3)Thefrequencies of K￣h allele and K￣L allele were 0.9381 and 0.0619 resp.and the gene heterozygosi-ty was 0.1161.
