The way in which the given process contributes to the growth of normal skeleton and in childhood and adolescence but causes immobility in adulthood. Introduction: Hyaline cartilage is an essential element lining the bones in the joints. Connective tissue leads to severe degenerative alterations in joints as there is no supply of blood. It is the solid substance lining the bones in a joint and the element that carries the stress in the moving parts. It is vulnerable because it is entirely dependent on the constant supply of fresh synovial fluid to give nutrients and oxygen and eliminate waste products.

Explanation of Solution

Knee arthritis is a complicated situation of degeneration of the hyaline cartilage at the edges of the femur and tibia, which are significant weight-bearing bones. It usually develops after damage to the knee like a tear in ligaments, extreme weight, and inadequate diet. The disease is now frequent at every age group but severely affects the adults. As the treatment of osteoarthritis are a chronic illness and a significant cause of disability in older adults.

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:
