Scientists have discovered the gene responsible for causing this disease.
For genes that are evolutionarily more conserved, the use of the rice genome seems to be more promising.
Identification and characterization of a new blast resistance gene located on rice chromosome 1 through linkage and differential analysis.
Such cross-time effects are of interest regardless of the initial roles of genes or early experiences.
More recently the roles of specific genes in normal cardiogenesis been defined.
It may be that environments and genes ultimately express themselves via this type of mutual, dynamic mechanism.
First, it is very unlikely to be one gene, because of the evidence for genetic heterogeneity.
Thus, even if a homozygous hybrid genotype is fitter, it may be very unlikely to be established in the face of gene flow and recombination.
However, escalating divergence of the populations is unlikely in the presence of gene flow unless they experience persistently different selection pressures.
