One of the objectives of selection programs in bees is the conservation of the gene pool. The mother-daughter replacement induces a decrease in the rate of loss of sex alleles and the viability of the offspring compared to the population in which the replacement is random. The experiment was carried out in the 2022-2023 bee season. Two queen-breeding colonies and ten drone-breeding colonies were selected. Ten queens were reared from each queen rearing colony. From each drone breeding family, the semen obtained from ten mature drones was collected and homogenized. Each queen was inseminated with the semen obtained by homogenization. Queens were introduced into orphaned colonies of equal strength. In the bees resulting from these colonies, morphological and behavioural characters were measured and compared with those of the parental population. According to the statistical results, the difference between the average of the studied characters of the parental population and the descendant population was very significant.
