To differentiate: In between incomplete digestive tract and a complete digestive tract. Concept introduction: Digestion is the second stage of the food use in animals in which, mechanical and chemical breakdown of food takes place. The breakdown of food results from the action of grinding by teeth and by the digestive enzymes. Digestion results in the formation of energy and breakdown of food to smaller subunits, which are absorbed and utilized by the cells of the body.

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…
