You are studying a human disease that is inherited in an autosomal dominant fashion. You recognize that the disease maps to chromosome 10, so you obtain four DNA probes that hybridize to different chromosome 10 regions. A family in which the disease appears presents itself to a medical genetics clinic. DNA is extracted from eac

Dihybrid cross; find percentage of black fine hair when two mice heterozygous for both of these traits are mated.
In a certain set of lab mice, black hair is dominant to white hair, and coarse hair is dominant to fine hair. Determine the percentage of black, fine-haired offspring that will result if two mice heterozygous for both of these traits are mated. Draw a Punnet Square to support your answer.
See attached for full problem description You are given a genomic DNA from human with unknown function. You suspect this piece of DNA might code for a protein, but you are not sure which of the 6 frames are really coding. Which frame is most likely coding? Which is the most significant domain match? Does this prote
Use reciprocal blast (bi-directional best hit) to find the human RefSeq sequence ortholog for mouse RefSeq sequence NM_007527. Note you should limit the database to RefSeq and select the right organism. You can obtain NM_007527 sequence by searching Nucleotide for NM_007527 from the the NCBI website.
See attached file for full problem description. Note: Please do not use other sources for your answer (Eg: Wikipedia) and please answer in full (Not simplified sentences), I need to be able to understand what you are explaining. When you carry out the working, please use punnett squares and diagrams. Question 2 is the most i
