The direction of information flow through a neuron in response to input from another neuron. Introduction: A neuron is the basic functional unit of the nervous system. It is part of a complex network of specialized cells of the nervous system for the transmission of nerve impulses. It is a microscopic individual cell that has the ability to respond to a stimulus and convert it into an action potential.

Expert Solution

Explanation of Solution

The axons are long, slender projections in the nerve cell that carries information away from the nerve cell body to different neurons. Incoming signals from other neurons flows into the dendrites and cell body regions of most neurons.

Summary Introduction

To describe: The relationship between the presynaptic neuron and the postsynaptic neuron.

Expert Solution

Explanation of Solution

The neurotransmitters are endogenous chemicals released by the presynaptic neurons. These chemical signals are then released into the synaptic cleft and bind to specific receptors on the postsynaptic neurons.

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:
