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:
1- The polar section of a phospholipid is the part with the phosphate group. This is sometimes called the polar head of the molecule.
2- The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.
Explanation:
If the Earths polar Ice melts the ocean levels will increase because of the increased amount of water. Some peninsulas and islands would decrease because they would sink from the risen water.
Answer:
The correct option is d (photosynthesis)
Reason:
Photosynthesis and respiration falls in the category of bioenergetics and metabolism, because photosynthesis end product is glucose which is utilized in respiration to produce ATP.
Answer:
True
Explanation:
Every cell has got different sets of genes. Although they do have the same exact DNA. The set of genes expressed in a cell determines the set of proteins and functional RNAs it contains, giving it its unique properties.
