Genotypic ratio in dihybrid cross
WebMay 5, 2024 · As in a dihybrid cross, the F1 generation plants produced from a monohybrid cross are heterozygous and only the dominant phenotype is observed. The phenotypic ratio of the resulting F2 generation is 3:1. About 3/4 exhibit the dominant phenotype and 1/4 exhibit the recessive phenotype. 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.. Figure \(\PageIndex{1}\): (a) A true-breeding …
