Question

A naturalist visiting an island in the middle of a large lake observes a species of small bird with three distinct types of beaks.

Those with short, crushing beaks (BB) consume hard-shelled nuts, those with long, delicate beaks (bb) pick the seeds from pinecones, and those with intermediate beaks (Bb), consume both types of seeds though they are not as good at either.
Assume that this difference in beak morphology is the result of incomplete dominance in a single locus gene.
Which of the mated pairs below will have the best adapted offspring in a year in which most of the food available is in the form of hard-shelled nuts? Show all work.
- Long delicate beak (bb) x short crushing beak (BB)
- Intermediate beak (Bb) x intermediate beak (Bb)

Expert Solution

Step 1

Genetics is the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. All of an organism's genetic material, including its genes and other elements that control the activity of those genes, is its genome.
