Length and breadth of eggs were measured in ringed populations of the Great Tit. During a part of the study volume and weight were also measured, but this did not give additional information, viz. variation in specific weight of fresh eggs and deviations from calculated volume were within the limits

β¦ Synopsis
The explanation of the maintenance of the large amount of genetic variation in natural populations is a major problem faced by evolutionary geneticists. It is proposed that Nucella lapiHus would make a suitable model for the study of this problem. The presence of visible interpopulation variation in characteristics which can be utilised for such studies, is demonstrated at a particular geographic location. The importance of experimental design in studying genetic variation is emphasised.

The complete diallel cross among homozygous lines can be a useful tool to analyze the genetic architecture of natural populations. However, it represents the natural population only approximately, in particular if the number of lines is small and the analyzed traits exhibit inbreeding depression or
Continuing a study of the average coefficient of kinship and inbreeding among offspring from specified mother plants belonging to a population of monoecious, diploid seed-plants, the variances of these coefficients have been computed. The variance in kinship was considered among offspring from a sin
