Consider the following pathway to produce chemical X in mice.lack of chemical X causes mice to lose their fear of cats(hence itis a very rare condition). It is discovered that the genes forenzymes Q and R are on the same chrosome and are separated by 8 mapunits.
Chemical Q-----enzyme Qase---> Chemical R----enzymeRase------>Chemical X
A colony of mice that lack chemical X is located. These micehave the genotype qq rr. One of these mice is mated to a fully wildtype mouse. The offspring of this mating are Qq Rr and makechemical X. One of these Qq Rr mice is mated with a fullyrecessive qq rr mouse. What is the probability that the first offspring mouse of this mating will suffer from a lack of chemicalX?
