Question

Describe how to use the phenotype ratios to determine the percentage of offspring displaying each trait.

Answer 1

Okay, so let's say you are looking at two traits, Tall (T) vs. short (t) plants and Green (G) vs. yellow (g) pods. After doing a cross you get a 9:3:3:1 phenotypic ratio of tall,green:tall,yellow:short,green:short...

That means that 9/16 of your offspring were tall and green. So, you just divide 9 by 16 and multiply by 100 to get percentage, which is 56.25%.
