Phenotypic ratio 194058-Phenotypic ratio of f2 generation
Write the amount of homozygous dominant (AA) and heterozygous () squares as one phenotypic group Count the amount of homozygous recessive (aa) squares as another group 5a Write the result as a ratio of the two groups A count of 3 from one group and 1 from the other would give a ratio of 31 Punnet Square RatioN The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences The expression of a specific trait, such as stature or blood type, based on genetic and environmental influencesFor a variety of reasons, the phenotypic ratios observed from real crosses rarely match the exact ratios expected based on a Punnett Square or other prediction techniques There are many possible explanations for deviations from expected ratios Sometimes these deviations are due to sampling effects, in other words, the random selection of a nonrepresentative subset of individuals for observation Q Tbn And9gcr01m Vckbdnhlocf2b0xuudahgae
