Dominant and Recessive Genes
...control of a single gene. The clues that help determine this are that the stem is a single gene, and the leaf is a single gene. When the plant is grown, only two types were displayed (yellow and purple), leaving only two options which were those that looked like the parent. 3. If a single gene controls the mutant type, how will you determine which is the dominant and which is the recessive? The dominant gene is demonstrated by the most number of plants. The recessive gene is illustrated by the least number. There are many possible contributions to error in this lab. The first possible error and the largest margin of error is that of, you guessed it, human error. I am incompetent in the ways of biology and too moronic too water the Petri dishes correctly allowing over half of our plants to die. That mass genocide of plant death right there alone could have changed the outcome of the lab. Another possible human error could be some F1 generation plants were not cross pollinated as much as the others, or not as well, or did not receive as much water. Another error that could affect the outcome of this lab is whether the plants and Petri dishes were placed at a sp...
