Summary Introduction

To determine:

The type of microscope that is used to get the best image in the given scenario

Concept introduction:

The microscopes are used to study the structure of microbes and cells of various living organisms. In light microscopes, the light of visible range is used to observe the specimen.

b.

Summary Introduction

To determine:

The type of microscope that is used to get the best image in the given scenario

Concept introduction:

Beam of electrons is used in electron microscopy. The magnets are used to refract the electron beam. The beam passes through the specimen. A very thin slice of specimen is observed under electron microscopes.

c.

Summary Introduction

To determine:

The type of microscope that is used to get the best image in the given scenario

Concept introduction:

Electron microscopes are used to study the cellular structure of the organisms. A beam of electrons is used in electron microscopes. The image produced from electron microscope is black and white because there is no use of natural light.

Summary Introduction

To determine:

The type of microscope that is used to get the best image in the given scenario

Concept introduction:

Prions are the small infectious particles that are made up of disease causing proteins. Abnormal folding of proteins is found in prions. Prions can cause neurological disorders in human beings.

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:
