Sinkovic̆, Tomaz̆
Evolutionary aspect of meiosis and reasons for dominate sexual reproduction in higher plants are described. Conjugation of homologue chromosomes and recombination of genes in prophase of the first meiotic division are presented. Evolution of meiosis from mitosis is discussed. The problems of flower bud sampling for meiotic preparations are presented. Flower buds of Allium ursinum were collected in March and April 2008. Best results were obtained by sampling flower buds in the third week of March. For meiotic preparations the optimal length of flower buds was 1 to 1.5 cm. In April the flower buds were over-developed and we could observe developing pollen grains only.
