The effect of decreasing the blood flow due to lung tumor on Po 2 (partial pressure) of oxygen and Pco 2 (partial pressure of carbon dioxide) in the alveoli and interstitial fluid. Introduction: Alveoli are the smallest sac-like structure present in the lungs. The exchange of gases takes place in alveoli. The pressure developed in alveoli by the gaseous exchange is called alveolar pressure.

Question

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…

Summary Introduction

To determine: The effect of decreasing the blood flow due to lung tumor on Po₂ (partial pressure) of oxygen and Pco₂ (partial pressure of carbon dioxide) in the alveoli and interstitial fluid.

Introduction: Alveoli are the smallest sac-like structure present in the lungs. The exchange of gases takes place in alveoli. The pressure developed in alveoli by the gaseous exchange is called alveolar pressure.

Summary Introduction

To determine: The response of bronchioles to th lung tumor and whether the response of bronchioles can generate ventilation in the lungs.

Introduction: The air enters the nose during inhalation. After that, air moves to the nasal passage, pharynx, larynx, tracheas, bronchi, and bronchioles. After passing the bronchioles, the air enters the alveoli. The gaseous exchange takes place at alveoli

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:
