Whether this is cheating or not that some athletes move to high-altitude locations to train for races run at lower altitudes. Introduction Athletes are trained for long-distance run including marathon and cross-country skiers at high-altitude locations because the low oxygen levels at high altitudes stimulate increased production of red blood cells. Erythropoietin is a hormone produced by the kidneys. It helps in the formation of red blood cells. These red blood cells carry oxygen from the lungs to the other parts of the body. Kidney cells are sensitive to low oxygen level in the blood.

To determine:

Whether this will be cheating or not that advances in gene therapy may one day make it possible to modify athletes’ cell so that they may contain extra copies of the gene that produces EPO.

Concept introduction

Erythropoietin hormone is produced naturally in the body of humans and it increases the synthesis of red blood cells. Erythropoietin (EPO) is found in blood; a recombinant erythropoietin is also available in the market. Erythropoietin is a hormone produced by the kidneys. It helps in the formation of red blood cells. These red blood cells carry oxygen from the lungs to the other parts of the body. Kidney cells are sensitive to low oxygen level in the blood.

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW). If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?

None

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…
