Answer:
roan coat color in horses
Explanation:
Codominance is one of the Non-mendelian inheritance patterns in genetics i.e. does not follow Mendel's principles of inheritance. Codominance is a phenomenon whereby an allele is neither dominant nor recessive to another in a gene i.e. one allele is not phenotypically expressed over the other. Hence, both alleles are simultaneously expressed in their heterozygous state.
An example of codominance is the roan coat color in horses where the colored (B) and white (W) alleles are both dominant in the coat color gene, hence, the horse expresses both black and white coat phenotypes known as ROAN (BW). The black and white alleles are said to be CODOMINANT.

Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
