Explain how the inheritance patterns of many traits (such as petal color in snapdragons, or skin color in humans) cannot be acco
pantera1 [17]

Answer:

Petal color in snapdragon is an example of incomplete dominance and deviates from Mendel's law of dominance.

Skin color in humans exhibits a continuous variation and is regulated by more than one genetic loci.

Explanation:

Two alleles of a gene do not always exhibit the dominant-recessive inheritance as shown by Mendel. The alleles controlling the petal color in Snapdragon exhibit incomplete dominance since the allele "R" is not able to produce enough pigment in heterozygous condition to completely mask the effect of the recessive allele "r" Therefore, the heterozygous genotype "Rr" gives pink color to petals.

Mendel showed that each genetic trait is regulated by one gene and exhibit discontinuous variations. This is not followed by skin color in humans which is a polygenic trait with multiple genes regulating it. Here, a range of phenotype is present which is regulated by the sum total of the dominant alleles of all the genes involved controlling the melanin production.

Proteins can be visualized in many ways, each of which highlights a specific aspect of the protein. drag the terms on the left t
Nastasia [14]

Answer:

1. Space-filling

2. Ribbon model

3. Wireframe

4. Simple shape

5. Simplified diagram

Explanation:

"attached is the question"

A protein can be visualized using different types of models. The models you use will depend on what you want the viewer to understand.

A space-filling model would show all the atoms that composes a protein. This type of model makes use of spheres, emphasizing the globular structure of the atoms. They are proportional to the actual size of the atom they represent.  Each type of atom is a different color. Even the distances of the spheres are proportional to its size to help viewers better see the actual shape of the protein.

Ribbon model is also a 3D representation of a protein. It shows the only the backbone of the protein. It highlights the folds and coils in a protein, generally the organization. Some versions show the α-helices as ribbons and β-strands are shown as arrows.

Wire frame model is like the ribbon model but it also shows the side chains. It shows the different atoms that are involved. Thin wires show the bonds made between the atoms and the wires bend show the relative location of the atoms.

A simple shape focuses more on the function of the protein overall rather than the internal structures. The shape does not represent a particular protein, merely using a general shape to represent a protein.

A simplified diagram shows more detail than the simple shape. It shows the internal structures as well but like the simple shape model, it focuses more on the function of the protein. A version of it is a solid shape, which does not show the internal structure.
