In a particular plant species, single genes determine flower color and plant height and the genes are located on the same chromosome. A true-breeding plant that is tall with red flowers is crossed with a true-breeding plant that is short with white flowers. All of the offspring are short and produce red flowers. a. Determine which alleles for each gene are dominant vs recessive, and using your own symbols, indicate the genotypes of each true-breeding parent and the dihybrid offspring. b. Indicate what cross you would do to determine the distance in cM between the two genes. c. After carrying out the cross you indicated above, you get the offspring indicated below. Using these values, indicate the distance between these two genes in cM. 72 tall with red flowers68 short with white flowers 29 tall with white flowers 31 short with red flowers
