Re: Y versus y or who is the mutant


>Y is the mutated less functional gene and y is the wildtype gene 
>for green

I said that the yelow leaf gene is probably an inhibitor gene and it 
is NOT in the chlorophyll synthesis pathway.  The "Y" allele is the 
dominant functional gene that is active and inhibits chlorophtyll 
synthesis.  The "y" allele is the recessive non-functional gene.  

If you want to assume that the yelow leaf gene is a gene in the 
chlorophyll synthesis pathway, then the YY or Yy genotype would 
produce a green leaf and the yy genotype would produce a yellow leaf 
because it would stop chlorophyll synthesis because it could not take 
a precursor and convert it to the next compound in the pathway.

The yellow leaf gene is a dominant gene and dominant genes are usually 
considered to be genes that produce a functional enzyme.
