Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even if only one copy is present, while recessive alleles require two copies to express their trait.

Front

What is a Punnett Square used for?

Back

To predict the genotypes and phenotypes of offspring from a genetic cross.

Front

What is the genotype for a homozygous dominant organism?

Back

The genotype is represented as two identical dominant alleles, e.g., AA.

Front

What is the law of segregation?

Back

The law of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.
