Genetics Review Flashcardizz

Front

What is CoDominance?

Back

CoDominance is a genetic scenario where two dominant alleles are expressed equally in the phenotype of an organism.

Front

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

Back

The probability of producing heterozygous offspring is 50%.

Front

What is a genotype?

Back

A genotype is the exact genetic makeup of an organism, represented by alleles such as RR, Tt, or PP.

Front

What is NOT a possible genotype for someone with type B blood?

Back

I^AI^B is NOT a possible genotype for type B blood.

Front

What is the chance of a blue-eyed baby from two brown-eyed parents (Bb x Bb)?

Back

The chance of a blue-eyed baby is 25%.

Front

Define phenotype.

Back

Phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is Incomplete Dominance?

Back

Incomplete Dominance is a genetic situation where one allele does not completely dominate another, resulting in a blended phenotype.

Front

What are alleles?

Back

Alleles are different forms of a gene that can exist at a specific locus on a chromosome.

Front

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.

Front

What does homozygous mean?

Back

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