QUESTION 11 "Waxy endosperm (wx), virescent seedling (v), and shrunken endosperm (sh) are all recessive mutants in corn. Waxy and shrunken are both on chromosome 9, located 18 map units apart. Virescent is on chromosome 5 and is not linked to the other loci. A strain of corn that is homozygous for waxy and virescent is crossed to a strain that is homozygous for shrunken endosperm. The F1 were entirely wild type. An F1 individual was then test crossed to a strain that is homozygous for waxy, virescent and shrunken. Of 1000 offspring, how many of the offspring will be virescent and shrunken, but not waxy?" 205 430 230 215 200
