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.© BrainMass Inc. brainmass.com October 24, 2018, 8:37 pm ad1c9bdddf
In a dihybrid cross, we study genetics of two different traits together. In the above problem, we are studying two different traits: B/b for black/white hair and C/c for coarse/fine hair distribution.

Genetics: mutation and punnet square problems
6) Mutational changes were introduced in a single codon in the gene of T4 phage. The following amino acid substitutions were observed. By following the base changes in the codons determine the codon for each mutant. Assume each amino acid substitution resulted from a single base substitution. Codons for several amino acids are provided: UAG, UAA, and UGA are stop codons. No additional information is required to solve this problem.
7) A red kernel wheat plant is crossed with a white kernelled plant yielding F1 plant all red kernels. A self cross yields a 15:1 red: white ratio. A testcross yields a 3:1 ratio red: white ratio. Explain the results. Draw Punnet Squares for both the self and the test cross.View Full Posting Details
