Inbreeding, thus a prerequisite. Relatedness implies, of course, that the plants involved share one or more ancestors. It has already been noted in section 2.1 that mating of related plants may occur in random mating, but in that case it occurs as a matter of chance.

Assortative mating and disassortative mating,sitive phenotypic correlation for the trait involved between the mating plants. The genotypes of these plants for the loci controlling the expression for the trait will therefore tend to be similar With . there is a negative phenotypic correlation between the mating plants with regard to the conside

Random variation of allele frequencies,chapter, population genetic effects of a restricted number of plants, which constitute a genetically heterogeneous population, are considered. In small populations the allele frequencies for loci controlling traits not under selection pressure can be considered to behave as random variables. This ap

Selection,al modes of reproduction, of the genotypic composition of populations was derived on the basis of this assumption. In the present chapter this assumption is no longer made: genotypes may differ with regard to vitality and/or fertility. The models describing the development of the genotypic compositi

Quantitative variation, a clone, a pure line or an F. hybrid, there is a wide range of phenotypic values. For certain traits (quasi-continuous ones) one can easily distinguish different levels of expression, e.g. for the number of ears produced by different wheat plants; for other traits there is truly . of expression, e.

Effects of the mode of reproduction on the genetic variance,n as the sum of contributions due to the relevant single-locus genotypes:.Then var(.) = var(.). If cov(.., ..) = 0 for all . ≠ . = 1,..., . this simplifies to var(.)=var(.), implying that the variance of the genotypic values, underlying polygenically determined traits can be written as a sum of cont
