Inbreeding, in itself, actually increases phenotypic variation, as measured by the
variance of a trait (Box B), as long as the phenotype of a heterozygote does not
lie outside the range spanned by the homozygotes. This is merely because ...

THE GENETIC STRUCTURE OF INBRED POPULATIONS Numerous
investigators have used genotype frequencies at enzyme loci to estimate the
inbreeding coefficient in plant populations. As theory predicts, the frequency of
heterozygotes is ...

Inbreeding and outbreeding Pure self-fertilization, the most extreme form of
inbreeding, ultimately results in a population of homozygous genotypes and no
recombination (Chapter 5). Although populations of habitually inbreeding plants
