Table 2. Segregation of ASHH2/ashh2 in reciprocal crosses with wt.

a

Transmission of mutant allele (T) was calculated as T(observed)/T(expected).

b

Transmission efficiency (TE) calculated as observed number of transmitted mutant alleles (TEobs)/expected number of transmitted mutant alleles (TEexp). TEexp for the mutant allele correspond to the observed number of WT alleles transmitted in the reciprocal cross (Howden et al., 1998).

c

Expected frequency of defective male or female gametophytes in a ASHH2/ashh2 plant. Δ = 0.5 (1-TE)×100%.

d

Expected frequency of homozygous plant calculated from TE(obs)female and TE(obs)male.
