The interpretation of oxyhemoglobin dissociation curve, the reason for the shape of the graph and how it is used to show the amount of oxygen unloading as hemoglobin passes through a typical systemic tissue. Introduction: RBCs (red blood corpuscles) have a red pigment called as hemoglobin which helps in the transport of oxygen (O 2 ) and carbon dioxide to and from the tissues. Hemoglobin is a complex protein, which has two chains alpha and beta chains. There are four heme groups and each heme is bound to an O 2 molecule which is linked to a central ferrous ion. Therefore, one hemoglobin molecule can carry up to four O 2 molecules. The O 2 bound hemoglobin is called as oxyhemoglobin (HbO 2 ).

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…
