Answer: The correct answer is-

D. Human feet come in a wide range of sizes.

According to Mendelian pattern of inheritance, a trait or physical characteristic of an organism is governed by single gene loci.

In other words, a single gene that exist in two alternative forms (alleles that are dominant and recessive allele) depicts a particular trait (such as tall and dwarf height of pea plant).

In the given option D), the wide range of sizes of human feet depicts polygenic trait (as it shows variation) that it is controlled by more than two genes (unlike Mendelian inheritance, which is controlled by single gene).

Thus, option D) is an example of Non - Mendelian pattern of inheritance.

D: Human feet come in a wide range of sizes. There isn't a lot of gray area or space for ranges of things in medel's laws, but they still work in a lot of cases.

beks73 [17]

Yes they would help predict and explain patterns of change in the size of populations for other large consumers.

<h3>What is Population?</h3>

This is defined as the total number of organisms in an area over a given period of time.

The population of producers and primary consumers help predict that of larger consumers. The higher their population, the lesser the population of large consumers that live in the Serengeti ecosystem.

Stella [2.4K]

Answer:

C) Primary, tertiary and quaternary levels of protein structure

Explanation:

Primary structure; Covalent bond is present in form of peptide bond in the primary structuture of proteins. The amino acids are held together in the polypeptide chain by peptide bond.

Tertiary structure; Disulfide bonds are present between cysteine amino acids, that keeps the parts of polypeptide chain strongly attached to one another.

Quaternary structure; The Quaternary structure of protein is held together by hydrophobic interaction and disulfide bonds.
