Front

What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles from the parents.

Front

What does genotype mean?

Back

Genotype refers to the genetic makeup of an organism, represented by letters that indicate the alleles present.

Front

What does phenotype mean?

Back

Phenotype refers to the observable traits or characteristics of an organism, which result from the interaction of its genotype with the environment.

Front

What is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even when only one copy is present in the genotype.

Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present in the genotype.

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 significance of capital letters in genetics?

Back

Capital letters represent dominant alleles in genetic notation.

Front

What is the significance of lowercase letters in genetics?

Back

Lowercase letters represent recessive alleles in genetic notation.

If a plant has the genotype 'Ff', what are its possible gametes?

Back

The possible gametes are 'F' and 'f'.
