Rosa canina is a wild rose. The fact that most roses in our gardens have ample petals? While wild roses have a handful of petals (five in this case),? The main reason is that garden roses are bred variants that hardly could survive in the wild. Most of their stamens have mutated to become petals. The wild rose is a Rosa canina, or “dog rose,” and has some other exciting features that are not apparent when looking at it. The name may have something to do with the fact that it was once used to treat the bites of rabid dogs.
It was hardly very effective, but that infrequently stops people from trying. It’s fruit, and the rosehip can be used for making jam and tea. As it contains a high level of vitamin C, it is considered a known nutritious food. Genetically, this is an extremely confusing little flower. In almost all human cells, like in most other animals and plants, there are two sets of chromosomes, Having two sets of chromosomes is actually called “diploid.”.
Rosa canina is pentaploid, which means that it has 5 sets of identical chromosomes. I have no exact idea why it thinks that is a decent idea. The pollen contributes only one genome. While the egg transmits four genomes in an arrangement without any respect for the equality of the sexes,. In this hodgepodge, there are 7 chromosomes that seem to be paired, while the rest prefer to stay single. It is absolutely nothing that one would think spontaneously when looking at this inconspicuous little rose. But if somebody offers you Rosa Canina for you’re birthday/anniversary, you can now amuse them with particular interesting genetic facts about the flower.
