Dominant Traits – Meaning and Definition

---

Definition:

Dominant traits are those traits that are expressed or visible in an organism even if only one copy of the dominant allele is present.
These traits mask the effect of a recessive allele when both are present (i.e., in a heterozygous condition).

---

Meaning:

Every trait is controlled by genes, which come in pairs of alleles — one from each parent.
If one of the alleles is dominant, it will control the trait’s expression, even if the other allele is different (recessive).

In simple terms:
If an organism has one dominant allele, the dominant trait shows up.

---

Examples of Dominant Traits:

In a pea plant with Tt (Tall and short alleles), the plant will still be Tall, because Tall (T) is dominant.

---

Genotypic and Phenotypic Connection:

Only tt shows the recessive trait.
TT and Tt both express the dominant trait.

---

Summary:

Dominant traits are traits that appear in an organism when at least one dominant allele is present.
They override the expression of recessive traits in heterozygous conditions and are a key concept in Mendelian genetics.
