When you ride a bicycle, your foot pushes down on a pedal that’s 17.5 cm (0.175 m) from the axis of rotation. your force produces a torque on the crank attached to the pedal. suppose that you weigh 700 n. if you put all your weight on the pedal while it’s directly in front of the crank’s axis of rotation, what torque do you exert on the crank?

In sweet pea, gene c is responsible for color production and gene p is responsible for the purple color pigment. both of them are located on two different loci on different chromosomes. the flowers will be purple only when the plant has the genotypes as c_p_. no color will be produced with genotypes: ccpp, ccpp, ccpp, ccpp. thus, gene c controls the expression of gene p. what pattern of inheritance is exhibited here? a. pleiotropy b. epistasis c. multiple alleles
