The beaching of the pigment and the condition when it occurs. Introduction: Phototransduction is the phenomenon which start with the capture of photon of light by the visual pigment. A deep purple pigment called rhodopsin is the visual pigment of rods. The arrangement of the rhodopsin, is in a single layer in the membranes of outer segment of rods. The formation and accumulaion of rhodopsin is takes place in the dark. The oxidation of vitamin A to the 11 cis-retinal form, followed by the combination with opsin leads to the formation of rhodopsin. The process of phototransduction involves the capturing of light by means of three steps: pigment synthesis, pigment bleaching and pigment regeneration.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
