Incompletely Dominant Alleles: An intermediate inheritance in which heterozygous alleles are

Incompletely Dominant Alleles: An intermediate inheritance in which heterozygous alleles are both expressed, resulting in a combined phenotype. Boxer dogs that are brown with black stripes are referred to as brindle. The brindle gene shows incomplete dominance. The number and darkness of the stripes in brindle boxers is highly variable. Some have so many stripes they look almost black. Some have a medium number of stripes. Others have just a few stripes. You breed a brindle that has many stripes with another brindle that has only a few stripes. What is the phenotype of the litter of puppies (F1)? A. 1:2:1 few stripes: medium stripes: many stripes B. 1:1 few stripes: many stripes C. 100% medium stripes D. 100% many stripes

A water pipe bursts, flooding a Small Business Company utility room

A water pipe bursts, flooding a Small Business Company utility room and tripping the circuit breakers on a panel in the room. Small Business contacts Tom, a licensed electrocution with five years of experience to check the damage and turn the breakers back on. Without testing for short circuits, which Tom knows he should do, he tries to switch on a breaker. He is electrocuted and sues Small Business for damages, alleging negligence. Small Business may have a successful defense to the negligence claim. it it true or false

Thermoreceptors come in two basic categories – those that respond to heat and those that respond to cold. Which of the following statements about action potential on sensory nerves originating in a thermoreceptor is correct? (a)decreasing temperature increases the frequency of action potentials from a cold receptor (b)decreasing temperature decreases the amplitude of action potentials from a cold receptor (c)decreasing temperature decreases the frequency of action potentials from both cold and warm receptors (d)decreasing temperature lower both the amplitude and frequency of action potentials from a cold receptor. (e)decreasing temperature affects the frequency of action potentials from cold recceptor but not warm receptors

In any sensory system (sound, light, chemical), the lower limit of detection is often determined by the “background’ noise level” of the sensory system. One could think of this as signals that are generated by the sensory system in the absence of any physical or chemical stimulus. Which of the following respresents this background noise level of sensory inputs to the nervous system? (a)the largest graded potential that will not produce an action potential (b)the smallest amount of neurotransmitter that will cause a detectable change in the post-synaptic membrane potential (c)randomly generated action potentials on a sensory neuron (d)the smallest action potential that can be produced

Fly Lab (#6) Assignments #1 and #2 The following questions are

Fly Lab (#6) Assignments #1 and #2 The following questions are designed to help you become familiar with the operation of Fly Lab by studying the inheritance of traits in frut flies. The purpose of this laboratory is to simulate basic principles of genetic inheritance based on Mendelian genetics, to understand the relationship between phenotype and genotype, and how to construct punnet squares to determine characteristic phenotypic ratios. Follow the instructions in the lab manual and answer the questions below as you work through the FlyLab using the lab manual. Remember to show numerical data in tables or figures using the guidelines provided (“Data Presentation Basics” Powerpoint presentation found in the START HERE FIRST folder under the Lesson’s tab on the Angel website),, to explain the data in simple, clear, concise sentences, and to then answer the questions or draw conclusions using the data. Data always appears in the text in the form of a table or a figure not both as soon after it is mentioned as possible. References are cited in your responses not at the end of the lab report! Insert your responses in the green text boxes below. They will expand as you enter text as needed. Copy and paste figures from the lab simulations as needed into the green response boxes. Use the “Export Feature” of the lab, the select the text or figure using the click, drag, select features of your mouse, type ctrl C to copy to the clipboard, place cursor in destination document and type ctrl V to copy from the clipboard. If the “Export” command in the lab simulations doesn’t work for you turn off “ALL” of your popup blockers! Gene Symbols (Creation and Use) 1. A gene symbol shall consist of a base of one to three letters. Previously published gene symbols will have priority. Additional information can be appended as described below. 2. For cases in which one allele is dominant, the first letter of the base symbol shall be capitalized to designate the dominant allele while all lower case letters will indicate the recessive allele. For example big “A” for the dominant version of the gene and little “a” for the recessive allele. 3. For diploid individuals AA, Aa, aa would be the correct form for the genotype of a homozygous dominant, heterozygous dominant, and homozygous recessive individuals, respectively. Use different letters for different characters.
