Front

In a cross between an individual with type A blood and an individual with type B blood, what is the probability of producing an offspring with type O blood?

What is the phenotypic ratio in a dihybrid cross of complete dominance?

Back

9:3:3:1

Front

What is incomplete dominance?

Back

Incomplete dominance occurs when the heterozygous offspring exhibit a phenotype that is intermediate between the two homozygous parents.

Front

What is the phenotypic ratio in a monohybrid cross of incomplete dominance?

Back

1:2:1

Front

Define homozygous dominant.

Back

An individual is homozygous dominant when they have two identical dominant alleles for a particular gene.

Front

Define homozygous recessive.

Back

An individual is homozygous recessive when they have two identical recessive alleles for a particular gene.

Front

What is a dihybrid cross?

Back

A dihybrid cross is a genetic cross that examines the inheritance of two different traits, each represented by two alleles.

Front

What is the principle of segregation?

Back

The principle of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is the principle of independent assortment?

Back

The principle of independent assortment states that alleles for different traits are distributed to gametes independently of one another.
