How the body disposes of the hemoglobin from RBCs and the relation between this and bile pigments, fecal pigments, and the pigment of the urine. Introduction: The body is endowed with mechanisms to detect changes in its internal environment, to antagonize the changes, and to ultimately maintain a fairly constant internal environment. These mechanisms together are termed as homeostasis – the maintenance of a constant internal environment. The number of RBCs in the blood is maintained at a constant level by a balance between the supply of new RBCs by erythropoiesis and RBC death and degradation, which happens around their 120-day life.

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…
