phenotype is the observable expression of the genes, therefore the genotype is actually affecting the phenotype. Reason may be for phenotype variation are
1) allelic variation - due to different different allele in population, there may be phenotypic variation
2) environment variation- although genotype may be similar but due to environmental variation there may be different in phenotype.
what are 2 reasons a monogenetic disease can present with a range of phenotypes?
1.Continuous traits can be defined as: a)Having a wide range of possible phenotypes b)Having only a few distinct phenotype c)Traits that are not influenced by environment d)Traits heavily influenced by environment 2. Quantitative geneticists seek to answer general questions such as: a)To what degree do alleles at different loci interact with each other? b)How many genes affect the phenotype? c)What are the relative contributions to the phenotype by the genes? d)All of the above are general questions quantitative geneticists seek...
Provide two reasons why identification of DNA variants in cancer patients is relatively easy compared to other disease phenotypes, such as intellectual disability.
what is the term for underlying disease or condition thst is present at the time of the patients office visit
1. What potential problems can pelvic inflammatory disease (PID) cause? 2. What sexually transmitted diseases can cause PID? What other device can cause PID? 3. What two genes have been found to be related to breast cancer? 4. What signs and symptoms could be present in a patient with breast cancer? 5. Since I have been teaching microbiology, which has been about 14 years, the leading cause of sexually transmitted infections (STIs) in the US has changed. Over the years...
What can explain the phenomenon where the same genotype might give rise to different phenotypes? A. codominance B. pleiotropy C. complete dominance D. recessive lethal E. Incomplete dominance
What is the importance of eating whole grains? List at least three reasons. 1. ! 2. What is the importance of maintaining a variety of colors in your vegetable intake? 3. Why should you intake more whole fruit than fruit juices? List at least two reasons. 4. For each of the following,list two nutritional benefits and one health (disease prevention) benefit. Fish: Soy:
If protein is mutated and causes disease, what mechanism of drug can treat this disease?
Discuss reasons why crude mortality rates for cancer and heart disease would be higher in Florida than in other states. What types of rates would provide more accurate information and why?
For the cross in Part B, predict the frequencies of each of the phenotypes in the F1 progeny, and determine the genotype(s) present in each phenotypic class. Complete the diagram by dragging the correct label to the appropriate location. Labels can be used once, more than once, or not at all.
There are two notable reasons that pathogens have the "upper hand" in driving pathogen-host co-evolution. What are they? (Answers should be less than 5 words!) A model developed for chronic wasting disease in deer in Alberta estimated RO value to be 4.0 in some situations (Potapov 2015). Suppose there is a vaccine available for chronic wasting disease (there isn't, unfortunately). What is the critical vaccination threshold (Vcrit) for this disease? How would you interpret your result from part a? True...
