What is heterozygous condition?

A heterozygous condition occurs when an organism has two different alleles for a particular gene or trait.

In this condition, one allele is usually dominant and the other is recessive. The dominant allele expresses itself in the phenotype, while the recessive allele remains hidden.

For example, Tt is a heterozygous condition for plant height, where T represents the dominant allele for tallness and t represents the recessive allele for shortness. In this case, the plant will appear tall because the dominant trait is expressed.

Heterozygous conditions are important in genetics because they contribute to variation and help explain inheritance patterns in organisms.
