“…We will first revise predictions of effective size when the nonrandom contribution of parents is due to noninherited causes. Caballero & Hill (1992a) similar to those of Latter (1959) andHill (1979). Alternative derivations are given by Pollak (1977), Crow & Denniston(1988) and Nagylaki (1992, pp.…”

Effective population size is a key parameter in evolutionary and quantitative genetics because it measures the rate of genetic drift and inbreeding. Predictive equations of effective size under a range of circumstances and some of their implications are reviewed in this paper. Derivations are made for the simplest cases, and the inter-relations between different formulae and methods are discussed.

1. The effect of genetic sampling, when this sampling is without replacement, on variation in gene frequency is studied, and equations describing the genetic drift are derived. The effective size turns out to be about one greater than under sampling with replacement.2. The relation between ‘spread of genes’ and genetic drift is worked out.3. The University of Queensland control poultry flock is analysed by these methods.4. The design of control populations is discussed with particular reference to the relative importance of genetic drift and phenotypic sampling.

“…The asymptotic increase of inbreeding per generation was estimated using formula (5) proposed by Latter (1959) and Hill (1972;1979), in which the number of males and females mated is weighted by the variances and covariances of family size in the 4 breeding groups:…”

1. Cumulative inbreeding attributable to selection in a finite population after long-term reciprocal recurrent selection (RRS) and modified RRS (MRRS) was studied in two White Leghorn lines. 2. Pedigree information was analysed for a period of 24 generations. In one generation, progeny of full-sib, half-sib and unrelated pureline as well as reciprocal cross-line matings were produced. 3. The structure of the two pure lines, which have been consistently used as part of the commercial cross, was documented in terms of numbers of sires and dams mated to produce sons and daughters, and variance of family size. On average, 87 sires and 870 dams per generation were mated to produce offspring. 4. Cumulative inbreeding values determined from pedigree data were compared with estimates from effective population size and variation of family size. 5. The increase in average inbreeding over 23 generations was 11.9% for line A and 10.8% for line B or 0.49% per generation, based on pedigree data. 6. Estimates from family structure were slightly higher: 12.6% for line A and 12.0% for line B or 0.54% per generation. 7. The increase in inbreeding appeared to be linear and independent of the selection method (MRRS compared to RRS).
