A phenotypic ratio isa quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another. When a researcher would like to obtain the gene expression for generations of an organism, they use the phenotypic ratio obtained from a test cross. A test cross is a … See more How would one define phenotypic ratio? The correlation between the amount of offspring that will obtain certain traits or a combination of traits is referred to as the phenotypic ratio. This ratio is usually acquired by … See more Before knowing how to find a phenotypic ratio, one should know certain genetic terms: 1. Gene:This is what is inherited from a parent and … See more One can use either a phenotypic ratio calculator that is developed for specific crosses or using a Punnett square. Many times, calculations can be difficult since phenotypes are seen when numerous alleles are combined. … See more How to calculate a phenotypic ratio.
