The application relates to a
molecular marker M-428 related to identification of sex-reversed pseudo-male individuals of
Rana dybowskii and application thereof, and relates to the field of molecular markers. In order to solve the problem that sex-reversed pseudo-male individuals of
Rana dybowskii are difficult to identify at present, the application extracts the
genome of the left hind
limb muscle tissue of
Rana dybowskii, takes the extracted
genomic DNA as a template, and carries out a PCR amplification reaction with a primer pair containing the sequences shown in SEQ ID NO:1 and SEQ ID NO:2. The PCR amplification product is subjected to
electrophoresis detection through 3%
agarose gel, the amplification result has a 428bp band corresponding to the
nucleotide sequence shown in SEQ ID NO:3, the
phenotype male individual is a genetic male Rana dybowskii, i.e. a true
male individual. The
phenotype male individual missing the band corresponding to the
nucleotide sequence shown in SEQ ID NO:3 is a pseudo-male individual with
sex reversal from a genetic female to a
phenotype male. The phenotype
female individual missing the band corresponding to the
nucleotide sequence shown in SEQ ID NO:3 is a
female individual.
