question 15

Multiple Choice

The same gene that causes various coat patterns in wild and domesticated cats also causes a cross-eyed condition in these cats,the cross-eyed condition being slightly maladaptive.In a hypothetical environment,the coat pattern that is associated with crossed eyes is highly adaptive,with the result that both the coat pattern and the cross-eyed condition increase in a feline population over time.Which statement is supported by these observations?

• A)Evolution is progressive and tends toward a more perfect population.
• B)Phenotype is often the result of compromise.
• C)Natural selection reduces the frequency of maladaptive genes in populations over the course of time.
• D)Polygenic inheritance is generally maladaptive and should become less common in future generations.
