Complex Inheritance Patterns Flashcard

Front

What is the probability of offspring having type O blood if both parents are heterozygous for type A blood?

Back

25%

Front

What is the term for a trait where both alleles are expressed together?

Back

Codominance

Front

Provide an example of incomplete dominance in plants.

Back

Red and white flowers producing pink flowers.

Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype.

Front

What is an example of a X-linked genetic disorder?

Back

Colorblindness.

Front

Define codominance in genetics.

Back

A form of inheritance where both alleles in a heterozygote are fully expressed.

Front

What is the expected phenotypic ratio of a monohybrid cross?

Back

3:1 ratio of dominant to recessive traits.

Front

What is the difference between complete dominance and incomplete dominance?

Back

In complete dominance, one allele completely masks the effect of another, while in incomplete dominance, the phenotype is a blend of both alleles.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

The genetic constitution of an individual, specifically the alleles present.
