About the pectoralis major, latissimus dorsi, deltoid, teres major, and coracobrachialis. Introduction: There are nine muscles that cross the shoulder joint and end of the humerus. Out of these two are axial muscles and seven are scapular muscles. The axial muscles are pectoralis major and latissimus dorsi. While, our of the seven scapular muscles four are rotator cuff muscles, and the three are deltoid, teres major, and coracobrachialis.

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…
