Two genes of a flower, one controlling blue (b) versus white (b) petals and the other controlling round (r) versus oval (r) stamens, are linked and are 10 map units apart. you cross a homozygous blue-oval plant with a homozygous white-round plant. the resulting f1 progeny are crossed with homozygous white-oval plants, and 1,000 f2 progeny are obtained. how many f2 plants of each of the four phenotypes do you expect? blue-oval : white-round : blue-round : white-oval

In corn, the allele a allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow kernels. at a second gene, w-produces smooth kernels, while ww kernels are wrinkled. a plant with blue smooth kernels was crossed to a plant with yellow wrinkled kernels. the progeny consisted of 1447 blue smooth, 169 blue wrinkled, 186 yellow smooth, and 1510 yellow wrinkled. a. are the a and w loci linked? if so, how far apart are they? b. what was the genotype of the blue smooth parent? include the chromosome arrangement of alleles. c. if a plant grown from a blue wrinkled progeny seed is crossed to a plant grown from a yellow smooth f1 seed, what kinds of kernels would be expected, and in what proportions?
