What is Genotype? (Meaning and Definition)

Genotype:
A genotype is the genetic makeup of an organism. It refers to the set of genes or alleles that an individual carries, which determine specific traits or characteristics.

Key Points about Genotype:

  1. Genes and Alleles:

    • Genes are segments of DNA that control specific traits.
    • Alleles are different forms or variations of a gene.
  2. Homozygous and Heterozygous:

    • Homozygous: Both alleles for a trait are identical (e.g., AA or aa).
    • Heterozygous: The alleles for a trait are different (e.g., Aa).
  3. Genotype vs. Phenotype:

    • Genotype: The genetic makeup (like Aa, BB, cc).
    • Phenotype: The physical expression or traits observed (like eye color, height).

Examples of Genotype:

Basic Genetic Concepts & Terms

What is Genotype? – Meaning and Definition

Genotype refers to the genetic makeup of an organism — specifically, the set of alleles (forms of a gene) inherited from its parents that determine certain traits.


Definition of Genotype:

“Genotype is the complete set of genes or genetic material present in an organism, especially the combination of alleles for a particular trait.”


Key Points:


Example of Genotype:

So, BB, Bb, and bb are genotypes, and brown or blue eyes are the phenotypes (physical traits).


Genotype vs. Phenotype:

Genotype Phenotype
Genetic code (alleles) Observable traits (e.g., color)
Inherited from parents Result of genotype + environment
Examples: AA, Aa, aa Examples: Tall, Short, Green eyes

In Summary:

Genotype = Set of alleles that determine the potential expression of a trait.
