Table 2. Means and s.d. are reported for population outcrossing rate (t) and adult inbreeding coefficient (F) from a survey of published mating system studies that lacked maternal genotype information for progeny arrays.

Mean Progeny Array Size	Nt	Species Nt	Mean t	s.d. of t	NF	Species NF	Mean adult F	s.d. of F
<8	141	29	0.46	0.41	46	12	0.45	0.32
⩾8	422	92	0.71	0.26	66	27	0.03	0.23

Abbreviations: NF, number of observations of F; Nt, number of observations of t; Species NF, number of species from which the observations of F were derived; Species Nt, number of species from which the observations of t were derived.

Observations of t and F were from populations, species or morphotypes. Progeny arrays fell into two size categories: <8 or ⩾8. The same species could be present in both categories if progeny array size differed among populations and/or morphotypes.
