Summary Introduction

To analyze:

The major bones of the skeleton.

Introduction:

The internal framework of the body is provided by the human skeleton. The skeleton is composed of appendicular and axial skeleton. The axial skeleton includes rib cage, vertebral column, and skull. The shoulder girdle, pelvic girdle and limb bones together forms the appendicular skeleton.

The skull is composed of facial and cranial bones. The bone present in the top part of the skull is the cranial bone that protects the brain. The cranial bone consist of parietal, frontal, sphenoid, ethmoid and occipital. The facial bones include maxilla, mandible, nasal bones, zygoma and frontal bone. Facial bones forms the structure of the face. The bone present between the sternum and the shoulder blade is the collar bone also called clavicle. This is the only horizontally lying bone in the body. The central part of the chest is occupied by a bone called chest bone. This bones connects the cartilage with the ribs. There are 24 ribs present in the body that protects the thoracic cavity.

The thirty three segmented vertebrae together forms the spine or the vertebral column. The vertebral column provides stiffness to the body. The large irregular bone present in the center of the body is the hip bone. This bone allows body to sit, and support the weight of the body. The hand consist of three types of bones that are phalanges, metacarpal and carpal bones. The phalanges are present in the fingers of the hands and toes.

The middle part of the hand consist of metacarpal bones. The wrist is composed of the bones called carpal bones. The kneecap is called the patella, a flat triangular bone that articulates with the femur. The patella provides protection and covers the articular surface of the knee joint. The bones in the foot are tarsals, metatarsals and phalanges. The ankle of the foot consist of bone called tarsals. The metatarsals are the bones that connects the tarsals and phalanges.

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:
