question 38

Multiple Choice

A researcher tracks the escape behavior of a population of squirrels on campus across two generations.When she plots the escape behavior of the offspring generation against the parental behavior,she notes that the offspring's behavior exactly matches the parental behavior.Nonetheless,the narrow-sense heritability equals zero.How can the heritability equal zero in this example?

• A)The additive genetic variance equals zero.
• B)All the escape behavior alleles are fixed in the population.
• C)There is no phenotypic variation.
• D)A and B
• E)All of the above

Definitions:

Product Costing

Product costing involves determining all expenses related to the creation of a product, including materials, labor, and overhead, to establish its total cost.

Absorption Costing

In this accounting method, total costs of manufacturing, from direct materials and labor to both fixed and variable overheads, are completely absorbed into the product’s final cost.

Variable Costing

Variable costing is a cost accounting method that includes only variable production costs—direct materials, direct labor, and variable manufacturing overhead—in product cost calculations, excluding fixed overhead costs.

Production Costs

Expenses directly related to the creation of goods and services, including materials, labor, and overhead costs.
