| A dominant gene will appear in the phenotype even in the heterozygous condition |
|
|
Term
|
Definition
| The dominant allele expressed whenever present, either alone or in a pair. The recessive allele makes no contribution to the phenotype. |
|
|
Term
|
Definition
| A recessive gene will only appear in the phenotype if it is present at both loci. It is hidden in the heterozygote but passed to the next generation. |
