Aplication of The Hardy-Weinberg Balancing Formulation Using Mathematical Modelling

Abstract

The Hardy-Weinberg balance principle, states that alleles and genotype frequencies in a population will remain constant from generation to generation without any other evolutionary influence, this principle is mathematically written by G. H. Hardy and Wilhelm Weinberg to be (p + q)²= 1. This research was conducted
to determine the ability of students to compile mathematical models in solving biological problems relating to Hardy-Weinberg balance. The research design used was a one-shot case study experimental design. To determine the ability of students to compile mathematical models, and complete mathematical models used a test description of the proportion of alleles if there is dominance, the proportion of alleles multiple, and the proportion of sex-linked alleles, test items are arranged based on aspects in the cognitive domain. Students are considered correct in arranging mathematical models if in the student answers for each item there are all components included in the category of composing mathematical models, namely symbolizing known elements, formulating the elements in question, and determining the relationships between variables. It can be concluded that the ability of students to arrange mathematical models was moderate, and the ability to complete mathematical models was lacking.
