apple seedlings
(David Hershey) wrote in message . com...
Many apple cultivars are self-sterile so cannot self-pollinate. Apple
orchards of these self-sterile cultivars must contain a second
cultivar as a pollenizer. Therefore, seeds of some cultivars will be
hybrids of two cultivars. However, each seedling with two parents will
be slightly different because of the "mixing" of genes that occurs in
sexual reproduction.
A possible explanation of the lower quality of most hybrids is if bad
genes are recessive, so alleles (hope I'm using the word correctly) of
hybrids would contain two recessive bad genes.
Maybe the bad genes shall be weeded out by further selection.
