Figure 1

Diagram of canina meiosis. Dogroses with a pentaploid somatic chromosome number (2n = 5x = 35) produce haploid pollen grains (1n = 1x = 7) during microsporogenesis in the anthers and tetraploid egg cells (1n = 4x = 28) during megasporogenesis in the carpels. Fertilization of haploid pollen grains and tetraploid egg cells restores the pentaploid somatic level of the next generation. Bivalent forming chromosomes are presented in red, univalent chromosomes are presented in white, grey and black.
