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 homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene, such as AA or aa.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene, such as Aa.

Front

What is an allele?

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is the genotype?

Back

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

Front

What is the phenotype?

Back

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

Front

What is the purpose of a Punnett Square?

Back

The purpose of a Punnett Square is to determine the probability of an offspring inheriting particular traits from its parents.

Front

What does it mean if an organism is homozygous dominant?

Back

An organism is homozygous dominant if it has two dominant alleles for a trait, such as BB.

Front

What does it mean if an organism is homozygous recessive?

Back

An organism is homozygous recessive if it has two recessive alleles for a trait, such as bb.

What is the significance of the F1 generation?

Back

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