Genetics Test- Punnett Squares

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 from the parents.

Front

What does 'T' represent in genetics?

Back

In genetics, 'T' typically represents a dominant allele for a trait, such as tallness in plants.

Front

What does 't' represent in genetics?

Back

In genetics, 't' typically represents a recessive allele for a trait, such as shortness in plants.

Front

What is the genotype of a plant with two identical alleles for a trait?

Back

Homozygous.

Front

What is the genotype of a plant with two different alleles for a trait?

Back

Heterozygous.

Front

What is the term for the physical appearance of an organism?

Back

Phenotype.

Front

What is the term for the genetic makeup of an organism?

Back

Genotype.

Front

What is Incomplete Dominance?

Back

Incomplete Dominance is a type of inheritance where the traits of two alleles blend together in the phenotype.

Front

What is Co-Dominance?

Back

Co-Dominance is a type of inheritance where both alleles in a heterozygous organism are fully expressed.

If a plant is homozygous dominant for round seeds (RR), what will its phenotype be?

Back

Round seeds.
