During ascus formation in Neurospora, any ascospore with a chromosomal deletion dies and appears white in color. How many of the eight ascospores in the ascus would be white if the octad came from a cross of a wild-type strain with a strain of the opposite mating type carrying a. a paracentric inversion, and no crossovers occurred between normal and inverted chromosomes? b. a pericentric inversion, and a single crossover occurred in the inversion loop? c. a paracentric inversion, and a single, crossover occurred outside the inversion loop? d. a reciprocal translocation, and an adjacent-1 segregation occurred with no crossovers between translocated chromosomes? e. a reciprocal translocation, and alternate segregation occurred with no crossovers between translocated chromosomes? f. a reciprocal translocation, and alternate segregation occurred with one crossover between translocated chromosomes (but not between the translocation breakpoint and the centromere of any chromosome)?
