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.

Answer:
the basic functions performed by living organisms for their survival and body maintenence are called life process.
Explanation:
life process require energy which is provided by nutrition .
basic life processes are : nutrition , respiration , transportation , excretion .
Hypotonic, isotonic, hypertonic
these terms are connected to the solution concentration. hypotonic solution is the solution with low concentration (lower than the concentration of particles in the living cell of an organism). if you put a cell in such solution, that cell would baloon because of the water migrating inside willing to rebalance the concentrations. isotonic solution is the solution with concentration of particles equal to the concentration inside a cell. hypertonic solution has concentration of particles higher than a cell and putting cell in this solution makes it shrivelled because of the water flowing outside (willing to rebalance concentrations again).
that's a phenomenon of osmosis.
Homozygous is the condition that the offsprings would have, if both their parents contribute identical versions of a gene.
<h3>What is the difference between homozygous and heterozygous ?</h3>
- Homozygous and heterozygous are terms that are used to describe allele pairs.
- Individuals carrying two identical alleles (RR or rr) are known as homozygous.
- Individual organisms bearing different alleles (Rr) are known as heterozygous.
- Homozygous produce only one type of gamete whereas heterozygous produce two types of gametes.
