A scientist is studying two traits in a type of beetle: body texture and color. Smooth body (B) is dominant to bumpy body (b), and gray (G) is dominant to white (g).
A BbGg and a bbgg beetle mate and produce the following offspring:
Phenotype Number of Offspring
Smooth, gray 345
Bumpy, white 355
Smooth, white 148
Bumpy, gray 152
What is the percent recombination frequency for this cross?

How does upwelling affect coastal fisheries? upwelling damages nutrient supplies at coastal fisheries as the warm, nutrient-rich surface water is replaced by nutrient-poor, cold water. upwelling damages nutrient supplies at coastal fisheries as the cold, nutrient-rich surface water is replaced by nutrient-poor, warm water. upwelling improves the nutrient supply at coastal fisheries as the warm, nutrient-rich surface water replaces the nutrient-poor, cold water. upwelling improves the nutrient supply at coastal fisheries as cold, nutrient-rich water replaces the warm, nutrient-poor surface water.
