The correct answer is C. Trophic level
Explanation:
In biology, a food chain refers to a network that describes the relationship between the organisms in terms of food or the way organisms eat other and can be eaten. Because of this food chain are organized according to different levels that include producer organisms such as plants, herbivore animals such as rabbits, predators that eat other animals such as eagles and decomposers such as certain worms or bacteria. Each of these levels is known as a trophic level and describe the position of each type of organism in the food chain. Additionally, food chain guarantees balance in the ecosystems as it controls the population of species. Thus, the position in the food chain refers to a trophic level.
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.
