Subject: Re: apomictic?
When apomitic seeds where produced, the genes get the chance to grow to a
mature plant maybe at another place where maybe the chance to make sexual
propagation is greater . When this happens for the apomitic generation the
motherplant reach the target to conserve her genes in nature life.
