Question

Many wildflowers depend on pollinators, such as bees, moths, and hummingbirds, for the successful production of seeds. Penstemons have flowers that are well-suited to pollination by bumblebees. Their flowers provide a sugary nectar for the bees and are the right size and shape for a bumblebee's body. Suppose that scientists measured flower length and the concentration of sugar in nectar. They found that the variation in flower length was 25 and the variation in sugar concentration was 121. The genetic component of variation, Ve, for flower length was 23.5, and for sugar concentration, 45. Calculate the broad-sense heritability, H', for flower length and sugar concentration. Express Hº to two decimal places HP of flower length: Hp of sugar concentration: What conclusion can you draw from these results? Because variation exists in both of these traits, the traits will evolve rapidly. O Offspring should have sugar concentrations that are similar to their parents. Flower length is more influenced by genetic factors than sugar concentration is. Cuneonnantention in m inthanaad hudditional than Alanlanathi

Answer 1

Foss Suger concentration For flower length Vp = 25 VG = 23.5 Up = 122 VG = 45 42 = va = 23.5 25 0.94 (Flower length) H2 = H² = 0.37 (Sugas Coner) Conclusion from these results- - more influenced by genetic scegas concentration flower factors length is than
