Nos. of progeny producing wild-type and mutant pollen are shown together with the calculated transmission efficiency (TE, no. of mutant/no. of wild-type progeny × 100) through male (TEm) and female (TEf) gametes. Self and reciprocal crosses between heterozygous mutants and wild type are depicted with the female partner shown first. s, TE values that differed significantly (P(x2 > X) = 0.001) from the expected value of 100%. ns, TE values that did not differ significantly (P(x2 > x) = 0.001) from the expected value of 100%. WT, Wild type.
