The plant is typically allogamous and consequently highly heterozygous. Markers for which a sire is heterozygous are indicated by 1, otherwise 0. Recombinational mapping is possible only in females doubly heterozygous for complementing t haplotypes. The number of heterozygous nucleotide sites maintained in a finite population due to steady flux of mutations. The number of heterozygous nucleotide sites maintained in a finite population due to the steady flux of mutations. In this experimental system, mutagenesis was followed by eight generations of growth in a mass culture when mutations with large heterozygous effects would be out-competed. Increased dominance also, of course, reduces the rate of the ratchet, because selection reduces the frequency of mutations even when they are heterozygous. There are two alternative haplotype reconstructions for a pair of loci for which a sire is heterozygous. Heterozygous knock-out mice for brain-derived neurotrophic factor show a pathway-specific impairment of long-term potentiation but normal critical period for monocular deprivation. All eight loci exhibited three or more abundant alleles and possessed a number of minor alleles in heterozygous combination with major alleles. This will tend to generate spurious correlations in the estimated fitnesses of the two heterozygous frequencies of the wild-type chromosome with the balancer. The data on heterozygous effects were collected from the present estimates gathered in both the dominance and epistasis studies. Only for nuclear families with e at least one parent heterozygous at the marker locus are the parents' phenotypes simulated. This is because these inversions are more frequently found in the heterozygous state, which suppresses recombination inside the inversions. These examples are from corpora and from sources on the web.
