<h3>What is a homo-zygous individual?</h3>
A homo-zygous is an individual who has the same gene variants or alleles for a given gene locus.
Conversely, a heterozygous is an individual who has different gene variants or alleles for a given gene locus.
In breeding, pure lines (or purebred) are homo-zygous individuals that may be crossed to obtain the desired trait in the descendence.
