Here's why:
* Allele: A variant form of a gene.
* Heterozygous: Having two different alleles for a specific gene.
Example:
Let's say a gene controls flower color, and there are two alleles:
* R: Red flower color
* r: White flower color
A plant with the genotype Rr would be heterozygous because it has one "R" allele and one "r" allele. This plant would likely display the dominant trait, which in this case, would be red flowers.
