Example of phenotypic ratio
WebApr 9, 2024 · These are the offspring ratios we would expect, assuming we performed the crosses with a large enough sample size. Because of independent assortment and dominance, the 9:3:3:1 dihybrid phenotypic ratio can be collapsed into two 3:1 ratios, characteristic of any monohybrid cross that follows a dominant and recessive pattern. WebExample Data. For this example, we will be using phenotypic data provided within the package. This consists of data collected from two woodlands each with 20 oak trees surveyed. The trees were manually assigned an oak decline status with 10 decline symptomatic and 10 decline non-symptomatic trees at each site.
