Summary Introduction

To answer: The factors that are essential for the normal production of red blood cells.

Introduction: Blood is an essential body fluid, which is the primary transport system of the body. It is involved in both pathological and physiological activities of all organs. The red blood cells or erythrocytes are one of the major components of the blood. It is necessary for the transportation of oxygen within the circulatory system. It possesses hemoglobin molecules that efficiently move oxygen from the lungs to other parts of the body.

Explanation of Solution

The factors that are essential for the normal production of red blood cells are as follows:

Dietary sources: Dietary sources such as vitamins (especially folate, riboflavin, B12, B6, ascorbic acid, pantothenic acid, and vitamin E), protein, iron, and minerals.

Intrinsic factors: The intrinsic factors are required for the absorption of vitamin B12 in the ileum.

Erythropoietin: It is required for stimulating the red blood cell production.

Functional bone marrow: The bone marrow should be functional for the production of erythrocytes.

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:
