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 a phenotype?

Back

The phenotype is the physical expression or characteristics of a genetic trait in an organism.

Front

What is a genotype?

Back

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

Front

What does a Punnett square represent?

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 is the difference between dominant and recessive alleles?

Back

Dominant alleles mask the effect of recessive alleles in the phenotype when both are present.

Front

What is Incomplete Dominance?

Back

Incomplete Dominance is a genetic situation where neither allele is completely dominant, resulting in a blended phenotype.

Front

What is a trait?

Back

A trait is a specific characteristic of an organism, which can be influenced by genetics.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to variations in traits.

Front

What is crossing over?

Back

Crossing over is a process during meiosis where homologous chromosomes exchange genetic material, increasing genetic diversity.

Front

What is Complete Dominance?

Back

Complete Dominance is a pattern of inheritance where one allele completely masks the effect of another allele.
