A scientist performs a series of mutation screens to look for mutations that reduce ATP production. One of the mutants, compared to a wild-type cell, has reduced levels of ATP and NADH and increased levels of FAD and pyruvate. Which hypothesis best fits these observations? -The mutation is disrupting glycolysis.
-The mutation is disrupting fermentation.
-The mutation is disrupting the citric acid cycle.
-The mutation is disrupting the electron transport chain.

What is the difference between sex-linked traits and autosomal traits in humans? a. sex-linked traits can only be passed from fathers to sons, while autosomal traits can be passed on from both parents to offspring of any sex. b. sex-linked traits are passed on through the x and y chromosomes, while autosomal traits are passed on through the other 22 chromosomes. c. sex-linked traits only affect females, while autosomal traits affect both males and females. d. sex-linked traits refer to genes that are on the x and y chromosomes, while autosomal traits refer to genes on all 23 chromosomes.
