SEEDS. “The seed is the product of the fertilized ovule, which in gymnosperms is naked, being borne on the surface of the scales that comprise the cone, whereas in the angiosperms the seed is formed within an ovary. In time the seed will normally become separated from the parent and eventually may germinate to give a new individual.” https://lnkd.in/d2V6VgJ View in LinkedIn

EXAMPLES OF HYBRID FITNESS. "A few examples of new phenotypes inferred to arise from hybridization include: extreme size of tiger x lion F1 hybrids; unique shapes and colors of hybrid orchids; ability of recombinant sunflowers to thrive in extreme habits; specialization on a novel host plant in lonicera flies; and expression of novel gene transcripts (including new exons) via alternative splicing in hybrid poplars." https://lnkd.in/dDz5VYD View in LinkedIn

NEW POSSIBILITIES ALLOWED. "Genetic recombination in hybrids can produce transgressive phenotypes, “monstrous” phenotypes beyond the range of parental populations. Transgressive phenotypes can be products of epistatic interactions or additive effects of multiple recombined loci." http://link.springer.com/article/10.1007/s11692-012-9209-0 View in LinkedIn

CREDIBLE HYBRID SPECIATION. "Recent empirical and theoretical research on hybrid speciation might have revived the hopeful monster in a new, more credible form. Recombination of parental chromosomes in the F2 and later generations during hybridization can generate genotypes that express phenotypes outside the normal range of variation observed in either parental gene pool, a phenomenon termed “transgressive segregation”.” http://link.springer.com/article/10.1007/s11692-012-9209-0 View in LinkedIn
