Expert Solution & Answer

Explanation of Solution

a. adduction:

The opposing movement that brings the limb across the midline or toward the body. The transverse is planes of motion in which the adduction of the shoulder girdle occurs. Vertical is the axis of rotation for the adduction in the shoulder girdle.

b.abduction:

Any movement of the limb or the body parts that pulla away from the midline is called abduction. The planes of motion for the abduction in the shoulder girdle is transverse. The vertical axis is the axis of rotation for the abduction in the shoulder girdle.

c. Rotation upward:

It is a rotation about an axis perpendicular to the scapula plane. The lower and upper section of the trapezius and the serratus anterior muscle are primarily accountable for upward rotation. The plane of motion for upward rotation in the shoulder girdle is frontal. The axis of rotation for the upward rotation is the sagittal axis.

d. Rotation downward:

The downward rotation is the rotation of the lower scapula towards the rib cage as in moving the arm behind the back. The plane of motion for the downward rotation in the shoulder girdle is frontal. The axis of rotation for the downward rotation is sagittal.

e. Elevation:

The elevation of the shoulder girdle is defined as the movement where the scapula moves in an upwards or superior direction occurring at the Sternoclavicular joints. The plane of motion for the elevation in the shoulder girdle is transverse. The axis of rotation for the elevation is the vertical axis.

f. Depression:

The reverse of the elevation movement is depression. The plane of motion for the depression in the shoulder girdle is transverse. The axis of rotation for the depression is the vertical axis.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
