Punnett Square

Front

What is the genetic makeup or allele combination of an organism?

Back

Genotype

Front

What allele combination should go in the missing box?

Back

Aa

Front

In pea plants, if the tall allele is dominant to the short allele, how would you represent this?

Back

Tall = T, Short = t

Front

What are Aa, DD, bB, yy examples of?

Back

Bb

Front

What is the observable physical characteristic of an organism called?

Back

Phenotype

Front

If a plant has the genotype Tt, what is its phenotype?

Back

Tall (since T is dominant)

Front

What is the purpose of a Punnett Square?

Back

To predict the genetic outcomes of a cross between two organisms.

Front

What does a homozygous genotype mean?

Back

An organism has two identical alleles for a trait.

Front

What does a heterozygous genotype mean?

Back

An organism has two different alleles for a trait.
