In the wrong song example ... A male cactus finch can learn the medium ground finch song. In a case where, a male finch does learn the wrong song. When the father dies and they learn the song of a male neighbor of a different species.

If a male finch learns the wrong song, it might mate with the wrong species, provided that their size and overall appearance are not all that different. The offspring of a cactus finch and medium ground finch would look like an intermediate between the two, but the song would not be an intermediate, it would be the same song the male parent sings!

These hybrid offspring are rare, and they are not as fit as either parent.
Can you think of why that is?

The collared lizard is a species found in the desert southwest. male collared lizards show considerable color variation, ranging from brightly colored to a very dull pattern. your goal is to determine the function, if any, of male color patterns in collared lizards, using the scientific method. your tentative explanation is that male color plays a role in attracting females for mating purposes. you predict that females will preferentially choose brightly colored males over dull-colored ones. to test this prediction, you observed the interactions of female collared lizards with their male counterparts. you selected males that were the same age and size, and that differed only in their coloration pattern. you placed equal numbers of the two types of male lizards, bright and dull, in aquariums, along with one female lizard per aquarium. out of 350 aquariums observed, the female chose to mate with the brightly colored male 277 times, and the dull-colored male 70 times. in 3 instances, the females did not mate with either type. create a bar graph of your data, plotting the type of male (dull or brightly colored) on the x-axis. on the y-axis, plot the frequency with which each type of male was chosen by females. using this graph, answer the following question(s). is it reasonable to conclude (i.e., is it supported by the data) that female collared lizards prefer more brightly colored male lizards over dull-colored males?
