↵a Fertile animals produced at least one viable offspring.
↵b Number of progeny hatching per adult.
↵c Newly fertilized embryos were collected at 15° and shifted to 25°. The fertility, brood size, incidence of male progeny, and embryonic lethality were measured by examination of the F1 progeny.
↵d lin-41(tn1487 ts) adults lay 139.7 eggs per adult (n = 32), with 75.9% hatching at 15°.
↵e lin-41(tn1487 ts) adults lay 9.8 eggs per adult (n = 29), with 39.1% hatching at 22°.
↵f lin-41(tn1487 tstn1536) adults lay 29.1 eggs per adult (n = 39), with 20.1% hatching at 25°.
↵g lin-41(tn1487 tstn1539) adults lay 57.3 eggs per adult (n = 40), with 27.3% hatching at 25°.
