- What is the difference between a monohybrid and a dihybrid cross? Monohybrid: hetereozygous for a single character Dihybrid: heterozygous for two characters - How many unique gametes can be produced through independent assortment by an  individual with the genotype AaBbCCDdEE 2 to the power of number of heterozygous True: the observed recombination frequency that are far away from each other has a max of  50% True: two of the traits medel studied, seed color and flower color, are linked on the same  chromosome - A frequency of recombination of 50% indicates that the 2 genes are likely located on  different chromosomes - If offspring are in ratio of 9:3:3:1, then are NOT LINKED (always dihybrids) o Know that its not linked, so f1 cross should produce9:3:3:1 ratio, but don’t o Ratio of offspring is 1:1:1:1 so 50% recombination frequency (all recombining in  high frequencies – recombining to the max) Recombination frequency = # recombinants/all recombinants
