Genetics Basics
Homozygous vs. Heterozygous:
1. Homozygous: Having two identical alleles (forms) of a gene (e.g., BB or bb)
2. Heterozygous: Having two different alleles of a gene (e.g., Bb)

Dominant vs. Recessive Traits:
1. Dominant: A trait that will be expressed if an individual has one or two copies of the dominant allele (e.g., B)
2. Recessive: A trait that will only be expressed if an individual has two copies of the recessive allele (e.g., bb)

Example:
Let's consider the trait for brown eyes (B) being dominant over blue eyes (b).

1. Homozygous dominant: BB (brown eyes)
2. Heterozygous: Bb (brown eyes)
3. Homozygous recessive: bb (blue eyes)
