In one type of plant, orange petals (O) are dominant over yellow petals (o) and tall stems (T) are dominant over short stems (t). Complete a dihybrid cross for parents with the genotypes: OOTt × OoTt and answer the following in complete sentences.
Describe how you would set up a Punnett square for this cross.
List the likelihood of each possible offspring genotype.
List the likelihood of each possible offspring phenotype.
Therefore the phenotype distribution is as follows: phenotype probability orange/tall 1/4+1/4+1/8 = 7/8 orange/short 1/8 yellow/tall 0 yellow/short 0 (Total 1)
