Green Genes

  Mr Eaton-  Your's and Lyle's examples are classcal mendelian genetics at its best.  Thank you so much for bringing this up, because this was the proof that I was looking for. 
 
Here is my take on the issue:  A green pumpkin is homozygous recessive for color, meaning that it contains two recessive alleles for color production, one from the mother, the other from the father.  The parents must have been heterozygous dominant for color production, meaning that each parent had one dominant allele and one recessive allele.  The dominant allele would mask the recessive allele and produce an orange pumpkin.   When these parents were crossed, there was a 1 in 4 chance the that the seed planted had the alleles for recessive homozygosity.  The odds are against a green pumpkin, but this time it showed through. 
 
This goes to demonstrate how certain traits are passed on through the generations, and if the right combinations are made, they eventually show through.   In this case it was 6 or 7 generations!!
Keep in mind that this is why we need to take a look at our seed heritages and make informed decisions about our crosses if you want the best for your pumpkin.
