So I have poured over the literature trying to determine the correct parentage for E4 and Gary.
From what I have found, it appears that there are two genes for the embryony of a mango, and the poly is dominant.
No organisms have been identified with homozygous poly genes.
So that means you can have Heterozygous Poly, or Homozygous Mono.
If you cross two poly parents, of four offspring, 3 will be poly, 1 will be mono.
If you have two mono parents, all offspring will be mono.
If you have one mono parent, and one poly parent, half of the offspring will be mono, and half will be poly.
Anyone else confused?
Pettigrew if it is the correct pollen parent of Gary and E4 must be Poly correct? Maybe there's more going on.
