describe outcomes of monohybrid crosses involving simple dominance, using Mendel’s explanations
Monohybrid crosses involve one factor only. For example, a cross might involve a true breeding (homozygous) tall plant crossed with a true breeding (homozygous) short plant. This produces a first generation where all of the plants are tall. Mendel explained the first generation trait as the dominant factor.
Thus, Mendel was able to explain his observed ratios, i.e.:
F1 – all tall
F2 – 3 tall : 1 short
