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.

What does 'dominant' mean in genetics?

Back

A dominant allele is one that expresses its trait even when paired with a recessive allele.

Front

What does 'recessive' mean in genetics?

Back

A recessive allele is one that only expresses its trait when paired with another recessive allele.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is a phenotype?

Back

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

Front

What does 'homozygous' mean?

Back

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

Front

What does 'heterozygous' mean?

Back

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

Front

What is the significance of the letter 'Y' in flower color genetics?

Back

In this context, 'Y' represents the dominant allele for yellow flower color.

Front

What is the significance of the letter 'y' in flower color genetics?

Back

In this context, 'y' represents the recessive allele for white flower color.

Front

How do you determine the phenotype from a genotype of 'Yy'?

Back

The phenotype for 'Yy' is yellow flowers because 'Y' is dominant.
