Monohybrid Cross Practice

Front

What is Codominance?

Back

A type of inheritance where both alleles in a heterozygous individual contribute to the phenotype, resulting in a mix of both traits, such as red and blue flowers producing speckled flowers.

Front

What is the phenotypic ratio?

Back

The ratio of different phenotypes produced in the offspring from a genetic cross.

Front

What does it mean for an allele to be dominant?

Back

A dominant allele is one that expresses its trait even when only one copy is present in a heterozygous individual.

Front

What does it mean for an allele to be recessive?

Back

A recessive allele only expresses its trait when two copies are present in a homozygous individual.

Front

What is a monohybrid cross?

Back

A genetic cross that examines the inheritance of a single trait controlled by one gene with two alleles.

Front

What is the genotype of a homozygous dominant individual?

Back

The genotype is represented as 'AA', where both alleles are the same and dominant.

Front

What is the genotype of a homozygous recessive individual?

Back

The genotype is represented as 'aa', where both alleles are the same and recessive.

Front

What is the genotype of a heterozygous individual?

Back

The genotype is represented as 'Aa', where one allele is dominant and the other is recessive.

Front

If a homozygous dominant (AA) is crossed with a homozygous recessive (aa), what will be the genotype of the offspring?

Back

All offspring will be heterozygous (Aa).

Front

What is the probability of producing a homozygous recessive offspring from a cross between two heterozygous parents (Aa x Aa)?

Back

The probability is 25%.
