Table 2.

Progeny Segregation after Reciprocal Crosses of Wild-Type and TCTP/tctp Plants

Cross (♀ × ♂)	Wild Type^a	TCTP/tctp^a	χ² (1:1)^b
TCTP/TCTP × TCTP/tctp	496 (93.2%)	36 (6.8%)	397.74^c
TCTP/tctp × TCTP/TCTP	290 (53.2%)	255 (46.8%)	2.25^d

Transmission of the tctp mutant allele through the female gametophyte is unaffected, whereas transmission through the male gametophyte is greatly impaired.

Number of Basta-sensitive (wild type) and resistant (TCTP/tctp) plants.

χ² values for a Mendelian 1:1 ratio.

χ²_(1/0,001) = 10.823.

χ²_(1/0,1) = 2.71.
