Genotype and Phenotype

Front

What is a genotype?

Back

The genetic makeup of an organism, represented by the combination of alleles (e.g., DD, dd, Pp).

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by both genotype and environment (e.g., blue eyes, tall stature).

Front

What does 'DD' represent in genetics?

Back

A genotype that consists of two dominant alleles.

Front

What does 'dd' represent in genetics?

Back

A genotype that consists of two recessive alleles.

Front

What does 'Pp' represent in genetics?

Back

A genotype that consists of one dominant allele (P) and one recessive allele (p).

Front

What are dominant alleles?

Back

Alleles that express their traits even when only one copy is present in the genotype.

Front

What are recessive alleles?

Back

Alleles that express their traits only when two copies are present in the genotype.

Front

How are dominant alleles represented?

Back

By uppercase letters (e.g., A, B).

Front

How are recessive alleles represented?

Back

By lowercase letters (e.g., a, b).

Front

What is the relationship between genotype and phenotype?

Back

Genotype determines the potential traits (phenotype) of an organism, but environmental factors also play a role.
