Individual and population asymmetry parameters

Article Abstract:

Population and individual asymmetry parameters are discussed relative to the genetic basis of developmental stability, which is not well understood and for which a genetic model of stability has not been developed. Existing data sets for 11 invertebrates from 50 samples are investigated for correlation patterns for individuals and populations, and it was found, using Kendall's coefficient of concordance, that even with significant consistent differences in level of asymmetry among different characters, no evidence of significant concordance was found, so results point toward genetic basis of developmental stability's being taxon-, character-, and population-specific.

Diallel crosses reveal patterns of variation in fruit-set, seed mass, and seed number in Asclepias incarnata

Article Abstract:

Diallel crosses are discussed as seen in seed mass, fruit-set, and seed number in Asclepias incarnata. Patterns of variation were seen when plants from two populations of Ascelpias incarnata ssp. incarnata were hand-pollinated for the crosses. Interaction effects are consistent with the hypothesis that maternal plants give resources differently to seeds based on specific genotypes of embryos. The effects could have several causes.

Inter- and intra-individual character variation

Article Abstract:

Inter- and intra-individual character variation are discussed as the relate to the genetic basis of developmental stability. Across 11 invertebrate species, for a variety of characters, a significant concordance of character coefficients of variation among samples within a species was found, so it appears that some characters are consistently more or less variable than others.
