WebMonohybrid Crosses. A monohybrid cross is one in which both parents are heterozygous (or a hybrid) for a single (mono) trait. The trait might be petal color in pea plants. When conducting crosses, the first generation is called P (or P 0 ), the second generation is F 1 (F is for filial), and the next generation is F 2. Web1.5 Punnett Squares – 3:1 Ratio. The specific ratios seen in the monohybrid cross can be described using a Punnett square, named after R.C. Punnett who devised this approach. Given the genotypes of any two parents, we can predict all of the possible genotypes of the offspring. Furthermore, if we also know the dominance relationships for all ...
