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)?

Apopulation of black bears depends on salmon from a stream for food. if a drought causes the stream to run dry one year, how will this likely impact the black bear population?

Which statement best describes the relationship between an allele and a gene? question 1 a. an allele is a variation of a gene that can be expressed as a phenotype. b. an allele is the part of a gene that attaches to messenger rna molecules. c. an allele is a segment of a dna molecule that controls replication of a gene.

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
