Estimation aux moindres carrés des effets géniques chez un organisme diploïde—Un locus à deux allèles—Application àNicotiana tabacum

When the genotypes of the individuals in a population can be identified and thereafter quantified, direct estimates of the genetic parameters and of the genetic variability components can be obtained from a sample proportional to the population genotypic frequencies. In such a situation, covariances among relatives are not needed. This paper provides the complete least squares computational procedure for one locus and two alleles, with frequenciesp and 1-p, in a population in Hardy-Weinberg equilibrium. Data onN. tabacum are throughly treated.
