The term "unit determiners of genes" is not a standard term in genetics. It seems you might be referring to alleles, which are alternative forms of a gene.

Here's a breakdown:

* Gene: A segment of DNA that codes for a specific protein or functional RNA molecule.

* Allele: Different versions of the same gene. For example, the gene for eye color has multiple alleles, some coding for brown eyes, others for blue eyes, and so on.

* Genotype: The genetic makeup of an individual, represented by the combination of alleles they possess for a specific gene.

* Phenotype: The observable characteristics of an individual, determined by their genotype and environmental factors.

The term "unit determiners" could be interpreted as referring to the fact that each allele represents a "unit" of information that contributes to the overall phenotype. For example, if you inherit one allele for brown eyes and one allele for blue eyes, your eye color will be determined by the combination of these two "units" of information.
