Answer:
Option B
Explanation:
The mode of speciation exhibited by these mice might follow the allopatric or peripatric pattern in that since these mice are in some ways related as stated, it is possible species C has become isolated from a peripheral population (in this case a peripatric speciation) due to maybe some geographical changes (allopatric speciation in general) as seen in vegetation changes at each elevation level and also no gene flow occurs between these population. And this depends on the number of individuals that dispersed from the original population. If large, it might be mainly by genetic drift.
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>

Frog RBCs contain a DNA-bearing nucleus that is visible in the center of the cell. Human RBCs do not possess nucleus along with other cell organelles such as mitochondria, Golgi apparatus and endoplasmic reticulum in order to accommodate greater amount of haemoglobin in the cells. Denucleation of rbcs is an adaptation, Which makes the mammalian red blood cell effective at transporting oxygen/eliminating CO2.
The sex cells are called Gametes! Its on Google!
When air is heated up the molecules spread out and move faster, so heat rises because it is less dense than the cooler air around it.
