In my bio class, we're learning about genetics currently and watched a video demonstrating mendel's experiments with pea plants. Something in the video didn't seem right to me, and my biology teacher is horrible and couldn't understand my question. In the part of the video in question, it shows a plant which had been bred from one parent which was pure bred so that it's peas were smoothe, and one parent which was pure bred so that it's peas were wrinkly. In the F1 generation, the peas were all smoothe. To demonstrate that the recessive wrinkly pea gene hadn't dissapeared, they showed a plant which had been bred from 2 plants which were swinkly/smoothe hybrids. This plant had 3 smoothe peas and 1 wrinkly pea in the same pod. This was to demonstrate the 3 to 1 ratio that smoothe peas had to winkly peas when bred from 2 hybrid parents. However, the thing that confused me was the fact that there were 2 different types of peas in the same pod. I understand how if you beed 2 hybrids that you have a 75% chance of getting the dominant factor, but I didn't think that the dominant and recessive factors would show up partially in the same organism. To me, having 3 smoothe and 1 wrinkly pea in the same pod seemed like someone having 25% red hair and 75% black hair. So, is it possible to have wrinkley and smoothe peas in the same pod, or was that specifically planned that way to demonstrate a principle?
