Two bicycles approach one another, each traveling with a speed of 8.50 m/s. (a) If bicyclist A beeps a 315-Hz horn, what frequency is heard by bicyclist B? (b) Which of the following would cause the greater increase in the frequency heard by bicyclist B: (i) bicyclist A speeds up by 1.50 m/s, or (ii) bicyclist B speeds up by 1.50 m/s? Explain.
Genetics Lecture 7 Recombination Frequency Example: Genes A & B are linked and are 10 m.u. (map units) apart. If cross AABB x aabb is made, and the F1is test crossed, what is the expected distribution of the genotypes in the progeny Answer: If 1 is test crossed, our new parentals are AaBb x aabb. These are the four expected progeny. AaBb – 45% - Parental aabb – 45% - Parental 1% Recombo Freq = 1 m.u. Aabb – 5% - Recombinant aaBb – 5% - Recombinant We first convert the 10 m.u. to a percentage, 10%. This 10% accounts for the two recombinant progeny since it is under 50%. Before moving forward, we must first identify the two parental progeny before iden
