Untersuchungen zur Genetik eines Esterasepolymorphismus beiSaccharomyces cerevisiae

摘要

On the genetics of an esterase polymorphism ofSaccharomyces cerevisiae. The inheritance of unspecific esterases ofSaccharomyces cerevisaewas investigated by tetrad analysis. It was shown that the four bands, found in the strains investibated, and distinguished by their electrophoretic mobility, are controlled by two loci with two alleles each. The loci E1 and E2 segregate independently whereas E2 is closely linked to the ad2locus. The E1 locus could not be mapped; however, there was evidence for free recombination with the contromere.
