mothprogeny | R Documentation |
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.
mothprogeny
A data frame 60 observations and three variables:
number of male offspring
number of female offspring
location the moth/progeny was sampled
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.
