Answer:
In this Dihybrid Cross, homozygous dominant traits were crossed with homozygous recessive traits. This particular cross always results in the phenotypic ratio of 1:0:0:0 meaning that the offspring will all have both dominant phenotypes but will be carriers of the recessive phenotypes.

Answer:
A dihybrid cross is a cross between F
1
offspring (first - generation offspring) of two individuals that differ in two traits of particular interest.
For example : RRyy / rrYY or RRYY/ rryy parents result in F
1
offspring that are heterozygous for both R and Y (RrYy)
Thus, Mendel's dihybrid ratio is depicted by: 9:3:3:1
