Table 1.

F2 lethality segregates opposite visible marker bli-3, located 10 cM from the most skewed RIL marker. Genotypes of F2 progeny from selfing Bristol/bli-3 and Hawaii/bli-3 hermaphrodites were scored. Embryonic lethality from selfing Hawaii/bli-3 hermaphrodites was slightly greater than 25% because the visible marker introduces a small percentage of lethality.
