Here's a breakdown:
* Allele: An alternative form of a gene.
* Homozygous: Having two identical alleles for a specific trait.
Example:
Let's say a gene controls eye color, and there are two possible alleles:
* B: Brown eyes
* b: Blue eyes
A person with homozygous alleles for eye color could have either:
* BB: Homozygous dominant (brown eyes)
* bb: Homozygous recessive (blue eyes)
Key takeaway: A homozygous combination means both alleles are the same.
