So children<span> look like combinations of </span>their parents<span> because they are. Each </span>parent<span>gives half of </span>their<span> genetic material to </span>their children<span>. The combination makes a unique combination of </span>their parents<span> genes. The scientific study of how </span>traits<span> are passed from </span>parents<span> to </span>children<span> is called genetics.

If you wanted to obtain 100% roan calves, then it si required to cross parents who are homo-zygous (pure lines) for the genes associated with this trait.
<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.
