C9 Genetics Review

Front

What is a dominant trait?

Back

A dominant trait is one that covers up or masks another trait in a heterozygous condition.

Front

What are hybrids in genetics?

Back

Hybrids are the offspring of parents with different traits.

Front

What is co-dominance?

Back

Co-dominance occurs when two traits are expressed equally in a heterozygous individual.

Front

What does the Law of Independent Assortment state?

Back

The Law of Independent Assortment states that allele pairs in offspring will segregate independently of one another.

Front

What did Gregor Mendel do in his first experiment?

Back

Gregor Mendel cross-pollinated two true-breeding pea plants.

Front

What is a recessive trait?

Back

A recessive trait is one that is masked by a dominant trait and only expressed in a homozygous condition.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits.

Front

What is incomplete dominance?

Back

Incomplete dominance is when the heterozygous phenotype is a blend of the two homozygous phenotypes.

Front

What is a true-breeding organism?

Back

A true-breeding organism is one that consistently passes down specific phenotypic traits to its offspring.

Front

What is a Punnett square?

Back

A Punnett square is a diagram used to predict the outcome of a genetic cross.
