The kind of cross that the figure describes is a dihybrid cross.
There are different types of cross. In this case, we have a dihybrid one.
<h3>What is a dihybrid cross?</h3>
A dihybrid cross happens between two individuals, animals, or plants with two different pairs of genes.
In this case, the two sets of genes that crossed are:
<h3>Parent 1 gene pairs</h3>
- The h0m0zygous dominant RR
- The h0m0zygous dominant YY
The result is RY.
<h3 /><h3>Parent 2 gene pairs</h3>The h0mzygous recessive rr
- The h0mzygous recessive yy
The result is ry.
As a result, the cross is a dihybrid one because RY and ry, which are two heterozygous pairs that code for different traits, crossed.
RY x ry
