The distribution of the sodium ions and potassium ions across the plasma membrane. Introduction: The concentration of the Na + (sodium ions) inside the cell is less as compared to the interstitial fluid. However, the concentration of the potassium ions (K + ) is moreinside the cell than in the interstitial fluid. The unequal distribution of the ions is due to the presence of the sodium–potassium ion pumps, which are also called the Na + /K + ATPase (adenosine triphosphatase).

Summary Introduction

To review:

The distribution of the sodium ions and potassium ions across the plasma membrane.

Introduction:

The concentration of the Na⁺ (sodium ions) inside the cell is less as compared to the interstitial fluid. However, the concentration of the potassium ions (K⁺) is moreinside the cell than in the interstitial fluid. The unequal distribution of the ions is due to the presence of the sodium–potassium ion pumps, which are also called the Na⁺/K⁺ ATPase (adenosine triphosphatase).

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:
