In sweet peas blue flowers are the result of a dominant factor (r) and red flowers of its recessive allele (r). long pollen is due to the dominant factor (l) and round pollen to its recessive allele (l). a plant homozygous for blue flowers and round pollen is crossed with one homozygous for red flowers and long pollen. the f1 individuals were crossed to red flowered, round pollen plants (test cross).diagram this cross as though these genes were independently assorting and give the expected ratios. the actual results were: 23 blue, long; 153 blue, round; 155 red, long; 21 red, roundbased on the observed results are these genes assorting independently? if they are linked compute the cross-over frequency (map distance).
