Leave enough room in each box for two letters. From the counts, one can assume which phenotypes are dominant and recessive. 1/4 regular HH The alleles are co-dominate, so two R's, one R and one W, and two R's will all produce different phenotypes. Suppose that two parents who are heterozygous for a trait produce an offspring. Requirements. From the source of Khan Academy: Probabilities in genetics, Alleles and genes, The law of segregation. While the other one becomes the dominant gene. Bifido Punnett Square Calculator With this dihybrid cross example, we expect a ratio of 9:3:3:1 in phenotypes where 1/16th of the population are recessive for both texture and color while \(\frac{9}{16}\) of the population display both color and texture as the dominant. Only one trait is used in the genetic cross. In F 2 tall and dwarf plants in In the last column, subtract the expected heads from the observed heads and square it, then divide by the number of expected heads.
