Question

In several species of birds, the males show off their bright colors and long feathers. The dull-colored females usually pick the brightest-colored males for mates. Male offspring inherit their father's bright colors and long feathers. Compared to earlier generations, future generations of these birds will be expected to have a greater proportion of:

A) dull-colored males

B) dull-colored females

C) bright-colored males

D) bright-colored females​

Answer 1

Correct answer is: C

Answer 2

Answer: C) bright-colored males

Step-by-step explanation:

The scenario described is an example of sexual selection, a type of natural selection in which certain traits increase an individual's chances of attracting mates and reproducing. In this case, the bright-colored males are more likely to be chosen as mates and pass on their traits to their offspring.

Therefore, we would expect future generations of these birds to have a greater proportion of:

C) bright-colored males

The bright-colored males are more likely to be chosen as mates and thus have more opportunities to pass on their bright-colored traits to their male offspring. This would result in an increase in the proportion of bright-colored males over generations. The females, being dull-colored, do not impact the color of the male offspring in this scenario.
