GENOTYPIC COVARIANCES BETWEEN INBRED RELATIVES

Genotypic Covariances between Inbred Relatives.

VER nearly half a century numerous workers have considered covariances and/or correlations between genotypic values of relatives and have related these population parameters to more basic parameters descriptive of the Mendelian mechanism of inheritance for diploids and the modes of gene action. FISHER (1918) considered random mating populations and developed formulae for the correlations betwee...

Covariances between Arbitrary Relatives in Autotetraploids with Panmictic Disequilibrium.

In random mating autopolyploid populations which have not reached equilibrium, two alleles may be interdependent as a result of the phenomenon of gametic recombination, i.e. the maintenance through successive gamete generations of an association of two alleles from the same gamete in a source reference generation. Any two alleles are dependent by this relationship if they derive by descent from...

Inbred Relatives with Special Reference to Selfing

The covariance of inbred relatives from a population in linkage and identity equilibrium in the presence of dominance and epistasis is formulated using a similar procedure to that which B. S. WEIR and C. C. COCKERHAM used to derive a general expression for the genotypic variance. An alternative model based on the description of a genotype in terms of the homozygotes of its constituent alleles i...

A General Linear Model for the Genotypic Covariance Between Relatives Under Assortative Mating*

A linear model for the genotypic covariance between relatives under assortative mating comprising the "classical linear model" and the model of "selective assortative mating" is proposed. The general conditions on the genetical and developmental mechanisms of quantitative characters, as well as on selection and the mating system, on which the model is based, are explicitly stated and discussed....
