This is being investigated for traits in rice such as grain width and protein contents where significant genotype by environment interaction has been detected.
The environments were considered as random variables while the genotypes were treated as fixed variables.
Most genotypes recovered in this study occurred only once (25 of 40 genotypes; 62.5%).
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.
The precise expression of these changes was quite strongly influenced by the genotype of the host, presumably mediated through variation in levels of genetically-determined resistance.
The same is true for the frequency of missing marker genotypes : as this frequency grows, the precision and power of the analysis is reduced.
Table 3 shows the number of distinct genotypes that were observed among the six populations.
The proportion of each individual's genotype that originated from one of the other populations was estimated using the assignment tests.
