The effect of hole in heart as if the heart of a normally developed human fetus has a hole between left and right atria and in some cases the whole does not completely before birth. If it is not surgically corrected, how would it affect the O 2 content of the blood entering into the systemic circuit. Introduction: Heart is a muscular organ present in the left side of the breastbone. It pumps blood through the network of arteries and veins know as cardiovascular system. Human has four chambered heart in which two atria and two ventricles are present and are separated by a valve. Blood flow in human body is facilitated by double circulation.

Linkage in common bean 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…
