🌱 Mendel's Laws of Inheritance (Monohybrid Cross)

1. Law of Dominance

In a dissimilar pair of alleles (heterozygous condition), only one allele is expressed in the phenotype.

The expressed allele is called the dominant allele, while the unexpressed one is the recessive allele.


🧬 Example:
In pea plant, when a tall (TT) plant is crossed with a dwarf (tt) plant, all F₁ plants are tall (Tt).
Here, T (tall) is dominant over t (dwarf).

🔁 Exceptions to Law of Dominance:

1. Incomplete Dominance
2. Codominance

2. Law of Segregation (Purity of Gametes)

During gamete formation, both alleles segregate (separate) from each other.

Each gamete receives only one allele, and this segregation is independent and random.


🧬 Example:
In a Tt plant, gametes formed are either T or t, not both.
