Answer:
because the germs spread and when other people touch it and are carriers and they will probably get sick too
Explanation:
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

<span>The circulatory body system, otherwise known as the cardiovascular or vascular system, is composed of four major parts: the heart, arteries, and veins. The vital responsibilities of the said system is to circulate blood throughout the body, transport nutrients, and carry away waste for elimination. Circulation starts when the heart pumps out blood through the main artery aorta, into the lung capillaries for oxygenation, and throughout the body via the arteries. Besides oxygen, nutrients and metabolic products are distributed as blood circulates, waste is processed and soon after eliminated by the kidneys as blood circulates there, and un-oxygenated blood returns to the heart through the superior and inferior vena cava (veins), the whole cycle therefore carrying on.</span>
