Question

which of the following is an example of non - random mating? male birds singing a song to attract female birds a frog laying its eggs in a small pond. all male lions of the pride mating with female lions

Explanation:

Non - random mating occurs when individuals choose mates based on certain traits. Male birds singing to attract females shows mate - choice based on a trait (the song), which is a form of non - random mating. A frog laying eggs in a pond is about reproduction location rather than mate - choice for non - random mating. In a lion pride, if it were non - random, there would be more specific mate - choice criteria (e.g., dominant male) rather than just "all male lions mating".

Answer:

Male birds singing a song to attract female birds.
