Explain the Law of Dominance using a monohybrid cross.

According to law of dominance, When two separate allelomorphic forms (genes) are produced in an organism, only one exhibits itself in the F1 generation, which is called the dominant gene, while the other is called the recessive gene because it has no effect and remains masked.
A monohybrid cross occurs when a cross is done between two individuals with only one opposing character at a time. The alleles 'T' and 't' exist for the character 'height.' The letter 'T' stands for tallness, while the letter 't' stands for dwarfism. When a pure tall (TT) pea plant is mated with a pure dwarf (tt) pea plant in an F1 generation hybrid, the result is 'Tt,' which is tall due to the presence of the allele 'T.' This demonstrates that tallness has the upper hand over dwarfism.
