Abstract

The invention discloses a method for breeding kidding traits by utilizing 3-gene pyramiding effect. The method comprises the following steps: amplifying a 3' untranslated region of a stem cell factor (SCF) gene, an exon 7 of a III type transmembrane tyrosine kinase receptor (KIT) gene and an intron 1 of a kiss (KISS1) gene respectively by using three pairs of primers and by taking goat genome DNA as a template; judging the size of each amplification product by using agarose gel electrophoresis at the concentration of 1.5%; screening the site mutation of the amplification products of the three pairs of primers by a DNA sequencing technology; performing genetic typing and gene frequency analysis on the single nucleotide polymorphisms (SNPs) of three sites of the SCF gene, the KIT gene and the KISS1 gene by using polyacrylamide gel electrophoresis at the concentration of 10% and agarose gel electrophoresis at the concentration of 3.5%; analyzing the relationship between different genotype combinations and kidding quantity; and screening out the optimal genotype combination.

Description

technical field [0001] The invention belongs to the field of molecular genetics and breeding, and specifically relates to a method for breeding lambing traits of goats by utilizing the aggregation effect of 3 genes. The method uses PCR-RFLP and DNA sequencing technology to detect the 3' of the stem cell factor (SCF) gene of the individual being examined. Single-strand DNA base mutation polymorphisms in the untranslated region, type III transmembrane tyrosine kinase receptor (KIT) gene exon 7 and kissin (KISS1) gene intron 1, by analyzing different genotype combinations The relationship between the number of goats and the number of lambs, screen out the best genotype combination, analyze the matching methods of high-yield individuals with the best genotype combination, and then apply these matching methods to form a core group of multi-gene aggregated fine breeds of goats with multiple lambs . Background technique [0002] The low lambing rate is the main bottleneck restrict...
