General selection model¶
A population-genetic recurrence describing allele-frequency change from genotype-specific relative fitnesses.
Core Idea¶
The basic two-allele diploid model assumes a declared mating and viability scheme, generation timing and no omitted forces; dominance and frequency dependence enter through fitness assignments. Genotype frequencies are formed from allele frequencies, weighted by survival or reproductive fitness, normalized by mean fitness and projected back to the next generation’s allele frequencies. The abstraction is therefore identified by a declared carrier, a transformation or constraint over that carrier, and an invariant that tells an analyst whether the named structure is genuinely present.
Scope of Application¶
General selection model belongs to population genetics and is useful where the analyst can specify the typed population genetics carrier, including objects, relations, parameters, conventions, evidence, and comparison cases, then evaluate the population and locus, alleles and frequencies, ploidy and mating assumptions, genotype fitnesses and timing, mean fitness, recurrence or delta equation, dominance, equilibria and excluded mutation migration and drift are explicit. The scope is broad within that domain but bounded by the need for the population and locus, alleles and frequencies, ploidy and mating assumptions, genotype fitnesses and timing, mean fitness, recurrence or delta equation, dominance, equilibria and excluded mutation migration and drift are explicit. High-level population-genetics model only; no breeding, culturing or genetic manipulation procedure is provided.
Clarity¶
The abstraction clarifies a crowded vocabulary by making the population and locus, alleles and frequencies, ploidy and mating assumptions, genotype fitnesses and timing, mean fitness, recurrence or delta equation, dominance, equilibria and excluded mutation migration and drift are explicit the center of the account. A claim should name the carrier, the governing operation or relation, the applicable assumptions, and the recognition test.
Manages Complexity¶
Without the abstraction, an analyst must reason directly over many local details: the carrier roles, admissibility assumptions, competing conventions, derived invariants, boundary cases, and proof or validation obligations specific to General selection model. General selection model compresses them into the roles in the structural signature. That compression permits comparison across instances without erasing the variables that determine validity. It also exposes which details may be varied safely and which are constitutive.
Abstract Reasoning¶
- Identify the carrier. State what the elements, states, objects, or observations are: the typed population genetics carrier, including objects, relations, parameters, conventions, evidence, and comparison cases. Reject examples whose alleged carrier belongs to a different problem. 2. Lock the constitutive rule. Express the population and locus, alleles and frequencies, ploidy and mating assumptions, genotype fitnesses and timing, mean fitness, recurrence or delta equation, dominance, equilibria and excluded mutation migration and drift are explicit independently of one notation or implementation.
Knowledge Transfer¶
Knowledge transfers strongly among subfields of population genetics because they reuse the typed population genetics carrier, including objects, relations, parameters, conventions, evidence, and comparison cases, Genotype frequencies are formed from allele frequencies, weighted by survival or reproductive fitness, normalized by mean fitness and projected back to the next generation’s allele frequencies., and type the carrier, state every parameter and convention in the definition, test that the population and locus, alleles and frequencies, ploidy and mating assumptions, genotype fitnesses and timing, mean fitness, recurrence or delta equation, dominance, equilibria and excluded mutation migration and drift are explicit, compare the nearest accepted identity, and report counterexamples, uncertainty, and limiting cases.

Neighborhood in Abstraction Space¶
General selection model sits in a crowded region of the domain-specific corpus (16th percentile for distinctiveness): several abstractions share nearly its structure, so a description that fits it tends to fit its neighbors too.
