 For the answer to the question above, 
DD <-- all (homozygous) dominant 
dd <--- all (homozygous) recessive 

DD-X dd 

__d__d 
D Dd Dd 
D Dd Dd 

^your Punnett square 

since there is a dominant gene in Dd, Dd's phenotype will be of the dominant. Therefore, an all dominant allele X an all recessive allele will yield an all dominant phenotype offspring.

There is one allele dominant and one is recessive, so all offspring will show dominant traits.

What is Punnett square?

Punnett square is a square diagram used to predict the genotype of any organism.

There is one dominant allele DD

One recessive allele dd

The crossover will produce Dd, Dd, Dd, Dd

All offspring will show dominant allele.

Thus, There is one allele dominant and one is recessive, so all offspring will show dominant traits.
