question 7 of 25
a scientist studies a species of bird in which the males and females are about the same size. the females have plain colors and the males have bright colors. what can the scientist conclude about these birds?
a. the birds reproduce asexually.
b. the females choose mates.
c. the males choose mates.
d. the males compete to fertilize.

Explanation:

In many species where males have bright colors (often used for display), it is a sign of sexual selection. When females choose mates, males may evolve traits (like bright colors) to attract females. Asexual reproduction (A) is not indicated as there are males and females. If males chose mates (C), females might be more colorful. Males competing to fertilize (D) is more about physical combat or other means, not color - based selection. So, the bright colors in males suggest female mate choice.

Answer:

B. The females choose mates.
