This is a simple system model that demonstrates passing on a recessive allele to one's offspring.
Genotypes from parents are calculated via random numbers, which consequently determine the
expression (or lack thereof) of the recessive allele in their kid. If, by random chance, both
parents pass on the recessive allele, their kid will exhibit that recessive trait. This can be
tied to the inheritance of recessive genetic disorders in real life. When one recessive trait is
very rare, the chance of it being expressed is even more so, since the dominant allele will always
"wins out" against the recessive. There are no inputs for this model, but it may be run multiple
times to gain a better understanding of the concepts surrounding allelic patterns.
