These two organisms may have evolved by coevolution. The last option in the given question is the correct option. The Latin-American humming birds had to evolve as per their surroundings, otherwise they would have become extinct in that region. For that sole purpose they had to have the long and curved bills. The flowers needed the humming birds for their pollination. To attach with the legs of the humming birds in the region, the flowers had to become sharply curved. The humming birds had to come in contact with the flower while sucking the nectar. this helped the plants in their pollination process. so both became mutually beneficial to each other.
Is there a graph or anything we can use as a reference.
1. C) Both parents contributed a recessive allele
The offspring is homozygous for the recessive allele, which means it has two copies of it. Because each parent contributes one copy of the gene, this means that both parents contributed the recessive allele.
2. D) The offspring can be tall or short
The first cross between TT and tt will yield an F1 generation with the genotype Tt. When this generation is self-pollinated, the cross may result in the following genotypes:
TT, Tt, tt
Which means that the offspring can be tall or short.
