mothprogeny: Sex ratios in moth progeny.

mothprogeny R Documentation
Sex ratios in moth progeny.
Description
Data from a study of the progeny of light-brown apple moths (Epiphyas postvittana) in four localities in Australia. Each observation is the progeny of a single adult female moth.
Usage
mothprogeny
Format
A data frame 60 observations and three variables:
- male:
number of male offspring
- female:
number of female offspring
- locality:
location the moth/progeny was sampled
Note
The appearance of several progeny with few or no male offspring is thought to be due to a particular genetic condition, so that the sex ratios may be due to a finite or continuous mixture. See Lewis (1987) for details about the study and some statistical issues.
