In birds, wingspan is determined by two genes, one with complete dominance of one allele over the other, one with additive effects. Birds with genotype aabb has 16 cm long wingspan, whereas those with AABB has 20 cm long wingspan. A cross between AABB and aabb parents produced F1 with 19cm wingspan. Crossing the F1s produced F2 with the following phenotypes (in cm): 20.0     19.6     18.3     20.0     19.1     18.7     18.2     17.3 16.0     19.2     17.8     18.4     19.3     19.5     20.0     19.7

Angiosperm Reproduction

The process of sexual reproduction in flowering plants is known as angiosperm reproduction. In flowering plants, reproduction begins with pollination, or the transfer of male gametes (pollen) from the male reproductive organ (anther) to the female reproductive organ (pistil), and ends with fertilization of the female gametes (egg), which produces a zygote, which then grows to become a mature plant.
