The description of an individual's alleles for a particular gene is called their genotype for that gene.

Quick Scoop: Genotype in Plain Terms

When you zoom in on just one gene, every person carries a specific pair of alleles there (for example, AAAAAA, AaAaAa, or aaaaaa).

That exact pair is the genotype – it’s the genetic “code” you have at that spot, whether or not anyone can see its effect from the outside.

  • Genotype = the specific combination of alleles an individual has for a gene.
  • Phenotype = the observable trait that results (like eye color or blood type).

So if the question is: “What do we call a description of an individual’s alleles for a particular gene?”
The answer is: genotype. ✅

Tiny Story To Lock It In

Imagine a classroom where everyone turns in a secret two-letter code on a slip of paper: some write AA, some Aa, some aa.

Those letters on each slip are each student’s genotype for that gene, even if, say, everyone with AA and Aa looks the same on the outside.

TL;DR: We call the description of an individual’s alleles for a particular gene their genotype.
