What is homozygous condition?

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

This means both alleles inherited from the parents are the same. The condition can be either homozygous dominant or homozygous recessive.

For example, TT represents a homozygous dominant condition for tall height, while tt represents a homozygous recessive condition for short height.

In a homozygous condition, the trait expressed depends on whether the alleles are dominant or recessive.

Homozygosity is important in genetics because it helps determine how traits are inherited and expressed in offspring.
