The figure below shows the effect of an antagonistic pleiotropic mutation A. What would be the effect of a mutation B that delayed the onset of reproduction without changing the survival curve?
a. Genotypes carrying A and B would have a higher fitness than genotypes carrying A without B. b. Genotypes carrying A and B would have a lower fitness than genotypes carrying A without B. c. B would not have any effect on the fitness of individuals with A. d. We cannot determine the effect of B without the survival curve for individuals that are wild-type at the locus affected by A.
