Imagine that a single gene determines if you are able to play the guitar or not. The alleles for this gene are: G = can play guitar and g = cannot play the guitar

Keith is HETEROZYGOUS for the ability to play the guitar. His brother, Shane, cannot play the guitar and neither can their mother.

Based on this information, answer the following questions.

1. What is Keith's GENOTYPE?

2. Can Keith play the guitar?

3. What is Shane's GENOTYPE?

4. What is the GENOTYPE for the mother (of Keith and Shane)?

5. What is the GENOTYPE for the father (of Keith and Shane)?

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
