Genetic and phenotypic correlations in plants: a botanical test of Cheverud's conjecture
Article Abstract:
Genetic and phenotypic correlations in plants are discussed relative to a botanical test of the conjecture of J.M. Cheverud that phenotypic correlations have high probability of being fair estimates of genetic counterparts in many situations. A survey of the literature of 40 years for agriculture and evolution has been carried out to find the degree to which phenotypic correlations agree with genetic counterparts in plants, and it was found that traits from the same suite of characters were more correlated phenotypically and genetically than those from different suites.

A new approach to the study of genetic variability of complex characters
Article Abstract:
The prospects for the practical application of the new approach and the evaluation of the contribution of the genetic diversity to phenotypic variability in animals in natural populations are discussed. It is concluded that the new approach is developed, based on examination of the distribution of parental strains and the F (sub 1) and F (sub 2) hybrids in a multidimensional space and the determination of the directions corresponding to heterozygosity, epistatic and additive gene effects.

Genetic constraints on floral evolution: A review and evaluation of patterns
Article Abstract:
A study describes the capacity for floral phenotype to respond to selection through a review of published data on heritabilities and genetic correlations for several classes of floral traits in hermaphroditic plants. Among the findings is a significant heritability for all floral traits, with variation among them, as well as a tendency for heritability to vary with mating system, but not life history.
