      com.rubecula.darwin.domain.world.Expresser_Mendelian

All Implemented Interfaces:

Expresser

Direct Known Subclasses:

Expresser_Sex

public class Expresser_Mendelian
extends Expresser_

Lifespan: permanent. This class implements Expresser and models a simple Mendelian gene expression. By simple, we mean that there is a one-to-one correspondence between genes and their resulting traits. Genes and traits may be dominant or recessive. For this simple implementation of Expresser, there must be exactly two alleles in the locus of any gene to be expressed AND there must be exactly two variants in the character. Furthermore, the genes must be passed in to the express() method, one at a time. For more complex expression models, it is necessary to extend Expresser_, although it is also possible to extend this class. This type is named, obviously, for Gregor Mendel, the father of genetics.

Method Detail

express

public Trait express(Gene... genes)

Express (one) gene passed in [Note this class cannot handle calls to this method with multiple genes].

Parameters:

genes - the gene locus which we are trying to express.

Returns:

the expressed trait

Parameters:

gene -

Returns:

the trait expressed by the gene.

expressHaploid

protected Trait expressHaploid(Gene gene)

Parameters:

gene - XXX

Returns:

if all is OK, then we return a trait but this particular implementation always throws...

Throws:

DarwinException - TEST
