A monohybrid cross involves only one characteristic. Typically true breeding individuals for the trait and its normal allele are crossed in what is known as the P1 generation. The characteristics of the F1 are noted and then the individuals of that generation are selfed to produce an F2. Usually, the data ratios in the F2 generation can be analyzed and the methods or mechanisms of the hereditary transmission can be discerned from them. This section contains several different monohybrid crosses that you can run. See if you can determine the mechanism of inheritance. The final cross will provide you with information for obtaining the answers. Remember, the + symbol means the wild or normal allele of the mutant in question. Note that if the mutant is described in lower case letters, it is very likely recessive.
