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

Answer:
The correct answers are "The heart is posterior/dorsal to the sternum" and "The lungs are deep to the ribs".
Explanation:
It is not true that the heart is posterior/dorsal to the sternum. Actually, it is considered that the heart is deep to the sternum, as well as the aorta, vena cava, and thymus gland. On the other hand, the lungs are posterior/dorsal to the ribs. The lungs are located in the thoracic cavity, which is extending anteriorly and laterally to the ribs.
