WebApr 28, 2024 · A monohybrid cross, or breeding a long-stemmed pea plant with a short-stemmed pea plant, allows scientists, like Gregor Mendel, to determine the dominance of long stems or short stems. A monohybrid cross also permits scientists to evaluate how heterozygous offspring express the genes they inherit. WebA genetic cross diagram (F2 generation) All of the offspring of the first cross have the same genotype, Tt (heterozygous), so the possible combinations of offspring bred from these are: TT (tall), Tt (tall), tt (short) There is more variation in this cross, with a 3:1 ratio of tall : short buccleuch living heritage trust
