An individual that is heterozygous for flower color and for height (PpTt) is test crossed. What is the phenotypic ratio of the o
MrRa [10]

Answer:

9:3:3:1

Explanation:

This type of crossing that involves two characters is referred to as dihybrid crossing. Generally, when there is a dihybrid crossing for heterozygous genes for both parents, the phenotypic ratio is usually 9:3:3:1 as shown in the figure in the attached document below.

Assuming the colour is White (P) and Black (p) and the

Height is Tall (T) and short (t)

The possible phenotypes will be in the ration

9 - White and Tall

3 - White and short

3 - Black and Tall

1 - Black and short

It should be noted that phenotypic ratio (phenotype) describes the outward appearance (what can be see physically) and not the genetic make-up. Thus, where there is a dominant character like P or T, the recessive characters are not considered to have been expressed.
