What is a dominant trait?

Back

A dominant trait is a genetic characteristic that is expressed in the phenotype even when only one copy of the allele is present.

Front

What is a recessive trait?

Back

A recessive trait is a genetic characteristic that is expressed in the phenotype only when two copies of the allele are present.

Front

What does the genotype 'Gg' represent?

Back

The genotype 'Gg' represents a heterozygous condition where one allele is dominant (G) and the other is recessive (g).

Front

What are the possible genotypes for a round seed if round (R) is dominant to wrinkled (r)?

Back

The possible genotypes for a round seed are 'RR' (homozygous dominant) and 'Rr' (heterozygous).

Front

If an organism has the genotype 'Tt', which trait will be expressed?

Back

The dominant trait 'T' will be expressed.

Front

What is the phenotype of an organism with the genotype 'TT'?

Back

The phenotype will express the dominant trait associated with 'T'.

Front

How can you determine if a trait is dominant or recessive?

Back

You can determine if a trait is dominant or recessive by observing the phenotype in offspring when crossed with known genotypes.

Front

What is the significance of a Punnett square in genetics?

Back

A Punnett square is a tool used to predict the genotypes and phenotypes of offspring from a genetic cross.

Front

What does it mean for a trait to be homozygous?

Back

A trait is homozygous when an organism has two identical alleles for a specific gene.

Front

What does it mean for a trait to be heterozygous?

Back

A trait is heterozygous when an organism has two different alleles for a specific gene.
