Answer: a) most ducks had about the same amount of webbing on their feet as their parents
Explanation: Evolutionary changes, such as the development of webbed feet in ducks, occur gradually over many generations. Most offspring will have traits similar to their parents due to genetic inheritance. Occasionally, variations occur due to mutations or genetic recombination, and if these variations provide a survival advantage, they may become more common in the population over time through natural selection. However, in any single generation, most individuals will closely resemble their parents in terms of inherited traits.
