The two alleles at a locus for a gene
WebDominant and recessive mutations at the SSN20 locus were previously isolated as extragenic suppressors of mutations in three genes (SNF2, SNF5, and SNF6) that are required in trans to derepress invertase expression. All ssn20 alleles cause recessive, temperature-sensitive lethality. In this study we cloned the SSN20 gene, identified a 4.6 … WebThe physical location of a gene on the chromosome is called its locus (plural = loci).
