What is the genotype of a green pea pod if green is dominant?

Back

GG or Gg

Front

What does a Punnett square show?

Back

It shows the possible genetic combinations from a cross between two parents.

Front

What can be concluded if all offspring from a cross between CC and cc exhibit chestnut fur?

Back

Front

If a trait is recessive, how many parents must pass on the allele for it to be expressed?

Back

Both parents must pass on the recessive allele.

What is the phenotype of the offspring from a cross between TT and Tt?

Back

100% tall plants.

Front

Back

100% probability of green offspring.

Define homozygous. Give an example.

Back

Homozygous means having two identical alleles for a trait. Example: TT or gg.
