Genetic pollution and number of matings in a black honey bee ( Apis mellifera mellifera ) population

Genetic pollution and number of matings in a black honey bee ( Apis mellifera mellifera ) population 122 73 73 2 2 J. M. Cornuet A. Daoudi C.

The proportion of non-B genes in a sample of drones was used to measure the “genetic pollution” in the local population. Within the course of a breeding scheme of local bees, 99 queens, whose genotypes are BB, were naturally mated between April 25 and June 10, 1985 at la Tave (Gard, France). Twenty daughters-workers of each queen were analysed at the MDH locus. The frequency of the B allele in drones that mated with these queens is estimated by the proportion of workers with genotype BB and the genetic pollution by the cumulated frequency of the other alleles. The sampling variances of these frequencies involve a coefficient which is a function of the average number of drones mated with a queen. This latter parameter is estimated through the maximum likelihood method. In addition to the three well-known alleles, a rare allele (frequency=0.0055), possibly equivalent to the S1 allele described by Badino et al. (1983), has been found in three different colonies. Cumulating the frequencies of the non-B alleles results in an estimation of the genetic pollution equal to 0.0394 (±0.0071). This low value allows us to proceed to the next step of the selection project. The mean number of drones mated to a queen is 12.4 with a (10.4–19.3) confidence interval at the 90% level. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png TAG Theoretical and Applied Genetics Springer Journals

Abstract

Chevalet Station de Zoologie et d'Apidologie INRA F-84140 Montfavet France Laboratoire de Génétique Cellulaire INRA B.P. 27 F-31326 Castanet Tolosan Cedex France Summary In the south-east of France, local honey bees possess only the B allele at the MDH locus, whereas the races which are usually imported into this area do not have this allele. The proportion of non-B genes in a sample of drones was used to measure the “genetic pollution” in the local population. Within the course of a breeding scheme of local bees, 99 queens, whose genotypes are BB, were naturally mated between April 25 and June 10, 1985 at la Tave (Gard, France).

The sampling variances of these frequencies involve a coefficient which is a function of the average number of drones mated with a queen.
