Genotype vs. Phenotype

Genotype vs. Phenotype

A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.

Examples of Genotype:

Is eye color a genotype or phenotype?

The visible eye color is your phenotype, but it tells us nothing about your genotype. Multiple different genes affect eye color in humans, and any of them could manifest dominant or recessive traits in your phenotype - that is, the unique shade of brown in your eyes.

Is TT a phenotype or genotype?

Genotype SymbolGenotype VocabPhenotype
TThomozygous DOMINANT or pure talltall
Ttheterozygous or hybridtall
tthomozygous RECESSIVE or pure shortshort

Is hair color a genotype or phenotype?

A phenotype is your version of a trait. Blue eyes vs brown eyes and curly hair vs straight hair are examples of phenotypes. A genotype is your combination of genes that produce your phenotype. If you have curly hair, your genotype is two curly hair versions of the hair texture gene: one from mom and one from dad.

What does genotype AA mean?

The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive. In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”.

Which blood genotype is the best?

Health Tips

Is height a phenotype?

​Phenotype

A phenotype is an individual's observable traits, such as height, eye color, and blood type.

Is blonde hair a genotype or phenotype?

An individual's phenotype only includes expressed genes. For example, if an individual has one “brown hair” allele and one “blonde hair” allele, and they have brown hair, their phenotype only includes the expressed gene: brown hair.

Is AA a heterozygous genotype?

Individuals with genotypes AA and aa are homozygotes (i.e., they have two copies of the same allele). Individuals with genotype Aa are heterozygotes (i.e., they have two different alleles at the A locus).
