Back

An organism with two identical recessive alleles for a trait, e.g., 'tt'.

How can a flower be white if red (R) is dominant?

Back

A flower can be white if it has the genotype 'rr'.

Front

What is a monohybrid cross?

Back

A genetic cross that involves one trait.

Front

What is the difference between phenotype and genotype?

Back

Phenotype is the observable traits, while genotype is the genetic makeup.

Front

What does dominant mean in genetics?

Back

A dominant allele is one that expresses its trait even in the presence of a recessive allele.

Front

What is a dihybrid cross?

Back

A genetic cross that involves two traits.

Front

What is the significance of the Punnett square?

Back

It is a tool used to predict the genotypes of offspring from a genetic cross.

Front

What does heterozygous mean?

Back

An organism with two different alleles for a trait, e.g., 'Tt'.

Front

What is a phenotype ratio?

Back

The ratio of different phenotypes in the offspring of a genetic cross.
