* Heterozygous: An individual with one dominant allele and one recessive allele for a particular trait.
* Homozygous Dominant: An individual with two copies of the dominant allele.
* Homozygous Recessive: An individual with two copies of the recessive allele.
In dominant inheritance, the dominant allele masks the expression of the recessive allele. This means that:
* Heterozygous individuals will have the same phenotype (physical characteristic) as homozygous dominant individuals.
Example:
Let's say the trait is eye color, where brown eyes are dominant (B) and blue eyes are recessive (b):
* Homozygous Dominant (BB): Brown eyes
* Heterozygous (Bb): Brown eyes
* Homozygous Recessive (bb): Blue eyes
As you can see, both individuals with the genotype BB and Bb will have brown eyes, even though they have different combinations of alleles.
