What is a dominant allele represented by?

Back

A dominant allele is represented by a capital letter.

Front

What is the result of crossing a homozygous dominant allele (AA) with a homozygous recessive allele (aa)?

Back

All of the resulting offspring will be heterozygous (Aa).

Front

How many alleles does a child inherit from each parent for each trait?

Back

A child inherits 1 allele from each parent for each trait.

Front

What term describes the physical characteristics that result from genes?

Back

Phenotype.

Front

What does each box on a Punnett Square represent in terms of genotype probability?

Back

Each box represents a 25% probability of an offspring's genotype.

Front

What is a recessive allele represented by?

Back

A recessive allele is represented by a lowercase letter.

Front

What is the purpose of a Punnett Square in genetics?

Back

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

Front

What is the genotype of an organism?

Back

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

Front

What is the difference between homozygous and heterozygous genotypes?

Back

Homozygous genotypes have two identical alleles (AA or aa), while heterozygous genotypes have two different alleles (Aa).

Front

What is the phenotypic ratio expected from a monohybrid cross of two heterozygous parents (Aa x Aa)?

Back

The expected phenotypic ratio is 3:1 (3 dominant phenotype : 1 recessive phenotype).
