Here's a breakdown:
* Homozygous: Means having two identical alleles (versions of a gene) for a particular trait.
* Heterozygous: Means having two different alleles for a particular trait.
Example:
* Eye color: Let's say the gene for eye color has two alleles: "B" for brown eyes and "b" for blue eyes.
* Homozygous dominant: BB (two "B" alleles, resulting in brown eyes)
* Homozygous recessive: bb (two "b" alleles, resulting in blue eyes)
* Heterozygous: Bb (one "B" and one "b" allele, resulting in brown eyes, as brown is usually dominant)
