Here's a breakdown:
* Heterozygous: Means having two different alleles for a specific gene.
* Alleles: Alternative forms of a gene that determine a particular trait.
* Gene: A segment of DNA that codes for a specific protein, which in turn contributes to a trait.
For example, let's say the trait is flower color:
* One allele: Might code for purple flowers (let's represent this as "P")
* The other allele: Might code for white flowers (let's represent this as "p")
A heterozygous pea plant would have the genotype Pp, meaning it has one allele for purple flowers (P) and one allele for white flowers (p).
Because of this heterozygous condition, the plant will express the dominant trait, which in this case is purple flowers.
