If a hom.ozygous white horse [tex]C^WC^W[/tex] and a hom.ozygous black horse [tex]C^BC^B[/tex] are bred together, what is the likelihood that their offspring will be roan with both colors represented in their hair if this gene follows a codominant inheritance pattern?
A.) 50%
B.) 25%
C.) 100%
D.) 0%

Answers

Answer:

c

Explanation:

looked at the answer when i finished the test and got it wrong lol

The roan coat color in horses is also an example of codominance. A “red” roan results from the mating of a chestnut parent and a white parent. Therefore, option (C) 100% is correct.

What is co-dominant inheritance?

In the genetic phenomenon known as codominance, both alleles of a gene pair found in a heterozygote are allowed to fully express themselves. Because of this, the phenotype of the offspring is a combination of the phenotypes of both the mother and the father. As a result, the trait does not exhibit dominant or recessive characteristics.

The blue roan horse has hair that is both white and gray, whereas the red roan horse's hair is both white and a reddish-brown color. The hairs of the offspring take on the coloration of both of its parents' coats. This is a situation of co-dominance.

Therefore, the resulting heterozygous progeny will have a 100% codominant inheritance pattern.

Nucleic acids are assembled in the 5' to 3' direction during DNA replication. DNA replication is the process of duplication of DNA molecule.

What are Nucleic acids?

Nucleic acids are the biomolecules occurring in the chemical compounds which serve as the primary information-carrying molecules in the cells. Nucleic acids play an important role in directing the process of protein synthesis. The two main classes of nucleic acids include deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Nucleic acids can only be synthesized in vivo in the 5′-to-3′ direction and these can be assembled in the same direction in cell, as the polymerases which assemble various types of new strands generally rely on the energy which is produced through breaking the nucleoside triphosphate bonds to attach these new nucleoside monophosphates to the 3′-hydroxyl (−OH) group, through a phosphodiester bond.

what can be said about altitude, atmospheric pressure, and the partial pressure of oxygen? check all that apply.

Answers

As both altitude and atmospheric pressure increase, the partial pressure of O2 will decrease.

Though I could not locate the options online to provide an exact answer, I can offer a general overview of the question at hand.

The interactions between altitude and the partial pressure of oxygen are inversely proportional. This means that as one increases, the other will decrease. The proportion of oxygen is 21% of the air content at all altitudes. However, as the altitude increases, the atmosphere becomes thinner, meaning that the partial pressure of O2 will decrease given that 21% of a thinner atmosphere results in less oxygen.

On the other hand, the relationship between atmospheric pressure and oxygen is that they are directly proportional. This means that as one decreases, the other does as well. In this case, since atmospheric pressure is the sum of the partial pressures of all gases, we can conclude that as it decreases, so to will the partial pressure of oxygen.
