A genotype is the genetic makeup of an organism, represented by the alleles it possesses (e.g., AA, Aa, aa).

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype and environment.

What are alleles?

Back

Alleles are different forms of a gene that can exist at a specific locus on a chromosome.

What is a dominant trait?

Back

A dominant trait is a trait that is expressed in the phenotype even when only one copy of the allele is present.

Front

What is a recessive trait?

Back

A recessive trait is a trait that is expressed in the phenotype only when two copies of the allele are present.

What is a Punnett square?

Back

A Punnett square is a diagram used to predict the genotypes of offspring from a genetic cross.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene (e.g., AA or aa).

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene (e.g., Aa).

Front

What is the F1 generation?

Back

The F1 generation is the first generation of offspring produced from a cross of two parental (P) genotypes.
