Nonessential ribosomal proteins. (A) Representative tetrads dissected from sporulated heterozygous diploids lacking the specified gene are shown, with “+” indicating presence and “−” indicating absence of the specific gene. Arrows denote especially small (rps12Δ) colonies. (B) Representative tetrads dissected from sporulated doubly heterozygous diploids lacking one copy of each of the paralogous RPGs are shown, with uppercase “A” or “B” indicating that paralog A or B is present; lowercase “a” or “b” indicate that paralog A or B is absent. Genotypes were confirmed by PCR.
