Essay
Two albino strains of Neurospora crassa were isolated in two different laboratories.When either one was mated with wild type (orange)it produced 1/2 albino: 1/2 orange progeny.
a)What can you now deduce about the genetics of each of these albino strains?
b)Assume first that the two strains carry allelic mutations.Using appropriate symbols,diagram a cross of the two albino strains.Include the genotypes of the parents,a stick-and-circle diagram of the relevant chromosomes at metaphase I of meiosis,and the genotypes and ratios of the progeny.
c)Now assume that the two strains carry mutations in different genes,and that the genes are on different chromosomes.Answer the same questions as above.Assume that there are no crossovers between either gene and the centromeres.
