The system is important because it tells the rest of your body what to do
Yes it absolutely makes sense and it is correct. Although there are many more definitions of a gene out there but this one is not wrong.
Two alleles expressing exactly the same information for a trait are described as homozygous.
An individual is homozygous for an allele if the two alleles are identical. Two normal alleles or two alleles with the same variation can both be present in a homozygous genotype. When an organism is homozygous, it signifies that it possesses two copies of the same gene allele.
If an organism possesses two copies of the same dominant allele, it is said to be homozygous dominant, and if it possesses two copies of the same recessive gene, it is said to be homozygous recessive. For instance, there are two variants of the gene for seed shape in pea plants: one form (or allele) for round seed shape (R), and the other for wrinkled seed shape (r).

<h3>What is anatomy?</h3>
Anatomy is a science that deals with the structure of the body of living organisms. We know that the structure of the body of an organism holds a lot of connection to the evolutionary history of the organism hence it can be used to predict the behavior of an organism such as the kind of things that organism may feed on.
When you are able to compare the jaw structure of all the organisms, then you could clearly see the relationship between the given jaw structure and that of other species hence what the specie eats can be obtained by extrapolation.
