You are working with some hyperactive mutant mice which tend to bury 100 marbles/hour in sand when studied in captivity. Normal wildtype mice bury between 5-10 marbles/hour in sand. You identify the gene responsible for this behavior and want to study its inheritance pattern. You cross a true breeding hyperactive female mouse with a normal wildtype male mouse and cross the resultant F1 offsprings to produce an F2 generation. You study the behavior of the F2 individuals and report the following:
247 females which bury 55 marbles/hour
270 females which bury 111 marbles/hour
239 males which bury 105 marbles/hour
253 males which bury 10 marbles/hour
Explain the inheritance pattern of this trait. What F2 genotypes, phenotypes and ratios do you expect if you cross a hyperactive male mouse with a normal true-breeding wildtype female mouse?
