A cross between individuals that are heter0zyg0us for two different traits is a dihybrid cross. <em>A cross between two individuals that are heterozygous for eye and skin color would be an example of a _</em>dihybrid<em>_ cross.</em>
----------------------
Dihybrid crosses involve individuals that expresses two different traits and are heter0zyg0us for each of them.
So let us imagine we are studing the characters eye color and skin color. Let us assume that both of them are coded by single diallelic genes.
For eye color there is
- Dominant allele B that codes for brown eyes
- Recessive allele b that codes for blue eyes
For skin color there is
- Dominant allele A that codes for black skin
- Recessive allele a that codes for white skin
So, an individual that is heter0zyg0us for both of them, is BbAa.
If this person crosses to another person with the same genotype, we are talking about a <u>dihybrid cross</u>, because two dibybrid individuals are involved.
Cross: BbAa x BbAa
According to this information, we can aswer the question:
<em>When crossing two individuals that are heterozygous for eye and skin color we are referring to a</em><em> dihybrid cross.</em>

Symbiosis is defined as a win-win relationship between two different species.
B- Win-win is the correct answer.
Answer:
Cell theory is originally presented by Schleiden and Schwann and initially, it has only two points and after some time the third point added but with the discoveries in the field of biotechnology there are many other points that are accepted and known as the modern cell theory.
According to the cell theory, all organisms are made up of one of the multiple cells and arise from the pre-existing cells by the cell division. A cell is a basic unit of structure and function.
Other than these three there are several other points are drive with the help of discoveries regarding discoveries which is helping to form that DNA is the hereditary material that passes all necessary information to the next generation.
Eukaryotes have a nucleus and prokaryotes don't
