Chapter 15, Problem 13Q
Summary Introduction

To explain: The reason why signal transmission at the synapse would require dynamin.

Introduction: Neurons are the cells which are mainly focused to communicate with the other cells by using electrochemistry as their communication language. The junction between two adjacent neurons is called synapse where the pre synaptic neuron release neuro transmitter. A small bulge at the end of the terminal branch of presynaptic neuron is called synaptic knob. There are several kinds of proteins known to be involved in synaptic transmission. Dynamin is such a kind of synaptic transmission protein found in Drosophila and no transmission of signals would pass one neuron to its adjacent one without the help of dynamin.

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…
