Concept explainers
To analyze:
The preference of hummingbirds and bees among red and light pink flowers and the significant difference in their visitation rates. The reason for the preference of red flowers by hummingbirds.
Given:
The variation at a single locus called the yup caused color differences in the two species, which was found by the researchers. The gene of M. cardinalis allele C is recessive, whereas the allele L of the M. lewisii is dominant.
The genotypes CC were found to be red and the genotypes LC and LL were found to be light pink. The preference of the bees and hummingbirds were recorded. The graphs below show the visitation rates of the bees and hummingbirds.
Introduction:
Flower shows a variety of morphology having different color, structure, and texture. The morphology of flowers is decided by their genetic trait. Pollination plays an important role in the life cycle of the plant. It helps in fertilization of flowers. Pollination is carried out with the help of different insects, birds, and animals.
