The application discloses an application of an animal
domestication behavior related RRM1
gene mutant. Through
population genetics,
comparative genomics and ancient
genomics analysis, the cause variation of the strongest selected
gene of goat
domestication, namely, the RRM1
gene c.1020A>G
mutation, is determined; through association analysis with a
hybrid population with wild goat blood, it is found that the
mutation is significantly related to the
domestication behavior in the goat domestication process; and through construction of a mouse containing the RRM1 gene c.1020A>G
mutation, it is proved that the corresponding
mutant of the RRM1 gene obviously increases the domestication behavior of the mouse. The application provides a basis and lays a foundation for
phenotype selection of the domestication behavior and preparation of a tame
animal model.
