What about if l say dominant allele is Red (RR) and recessive allele is white(ww) then genotype is haterozygous is that correct

*   When representing alleles for the **same gene** (like seed color), we use the **same letter**.
*   The **dominant allele** is represented by a **capital letter**.
*   The **recessive allele** is represented by the **lowercase version of that same letter**.

*   If you say the dominant allele is Red, you would assign it a capital letter, for example, **R**.
*   If the recessive allele is White, you would assign it the lowercase version of that same letter, so **r**.
*   Therefore, a homozygous dominant individual would be **RR**.
*   A homozygous recessive individual would be **rr**.

*   A **heterozygous** genotype means an individual has **one dominant allele and one recessive allele**.
*   Using the correct symbols, a heterozygous genotype would be **Rr**.
*   Your statement "dominant allele is Red (RR) and recessive allele is white(ww) then genotype is haterozygous" is **incorrect** because:
    *   You used different letters (R and w) for alleles of the same gene.
    *   RR represents a homozygous dominant genotype, not just the dominant allele.
    *   ww represents a homozygous recessive genotype, not just the recessive allele.
    *   A heterozygous genotype would be Rr, not a combination of RR and ww.
