You and your lab partner have isolated 20 new mutant yeast strains that are defective in synthesis of threonine, an amino acid. These Thr- mutants do not grow on minimal medium, but they do grow on minimal medium supplemented with threonine. Ten of your Thr- mutants (numbered 1 through 10) were isolated in a strain of mating type a (MAT a). The other 10 Thrmutants (numbered 11 through 20) were isolated in a strain of mating type α (MAT α). You and your lab partner cross each of the MAT a strains to each of the MAT α strains, and you include crosses to the appropriate wild-type strains. Your experimental observations are shown in the table below, where (-) indicates diploids that did not grow on minimal medium and (+) indicates diploids that did grow on minimal medium.

Which mutations do you know to be in the same gene?

You are conducting genetic linkage studies of an autosomal recessive disease whose chromosomal location has not been firmly established. You are focused on two SSR markers that may be linked to each other and to the disease. Here are two families in which some individuals are affected:
                                       
Calculate LOD scores for linkage at θ= 0.02 between the disease and SSR42 in Family 1.

Blue follower is dominant over white flower and long pollen is dominant over short pollen. A plant with Blue flower and short pollen was cross with white flower and long pollen. Their progeny, ½ had a blue flower with long pollen and another ½ had a white flower with long pollen was allowed to intercross. Which of the following observation is correct among these progeny when independently assort?
