The Figure Below Shows the Effect of an Antagonistic Pleiotropic

question 9

Multiple Choice

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.
