In Drosophila melanogaster, eyeless (ey) is a recessive trait in which the eyes are tiny or absent. The ey locus is found on chromosome 4. Monosomy and trisomy for this very small chromosome are compatible with survival and fertility. A trisomic wild-type male with the genotype ey+ ey+ ey is crossed to an ey+ ey female. Assuming random segregation of chromosomes into gametes, determine the chromosome constitution and phenotypic ratios in the offspring.
