![]() ![]() He did not use that term, but in this case, the versions Now, today we know that theĭifferent versions of a gene, we call alleles, although That these factors could come in different versions. He did not use the term, and he also hypothesized So in this case it would be around height. Results, he hypothesized that there are inheritable factors that are inherited fromĪn organism's parents and they're related to a specific trait. This short trait reappeared in this second generation. First of all, at least for this trait, he didn't see any blending occur. Those weren't the exact numbers, but pretty close to three to one. Roughly there was a ratio of three to one, tall to short. In other words the same plant can be both the female parent and the male parent. So the same plant can contributeīoth the female gamete and the male gametes. But then when he selfįertilized those plants and plants have the interesting property that they can fertilize themselves. With short pea plants, all of the offspring were tall. ![]() Parent with a short parent, you would get a medium offspring, but that's not what Mendel saw. And in his time, the mainstream theory was that if you bred a tall ![]() Properties of the seeds, properties of the pea prods, and things like the height of the plant. Over that time period, heīred roughly 28,000 pea plants in order to get a better understanding of how they passed down different traits. His pea plant experiments that he conducted from 1856 to 1863. Glimpse, gave us insights in how traits are really passed. Of years before Mendel, but he really gave us a And many people had bred plantsįor agricultural purposes for hundreds, if not thousands And we'll see in a few seconds why, and he was an Abbot ofĪ monastery in Moravia, which is in modern day Czech Republic.
