海湾扇贝杂交、近交和自交家系的微卫星标记偏分离分析
Microsatellite segregation distortion analysis of the out bred,inbred and selfed families of the Bay scallop(Argopecten irradians)
摘要
Abstract
The bay scallop (A rgopecten irradians)is a hermaphroditic marine bivalve. It has male and female gonads simultaneously, and exerts external fertilization. So it has three breeding manners: outbreeding, inbreeding and selfing. In this study, 10 microsatellites primers were used to test the segregating distortion in two outbred, two inbred and four selfed families (three selfing for the first generation and 1 for the second generation). The outbred families were found to have the most segregated markers, followed by the selfed families for the first generation and the selfed-families for the second generations, and the inbred families were found to have the least segregated markers. The homozygote deficiency loci was only found in the selfed families, which means partial dominance may be the genetic basis of inbreeding, and we also found three markers might be linked to the lethal genes.关键词
