segregation ratio

Of these 28 schools ten had increasingly privileged intakes over time, as determined by their segregation ratios.

Genome coverage and potential causes of the observed segregation ratio distortions are discussed.

Ninety-five percent of the loci fit expected segregation ratios.

The loci with distorted segregation ratios were confined almost exclusively to a region of one linkage group.

A Χ 2statistic can be used to assess whether the segregation ratio of a particular marker differs significantly from expectation.

Possible explanations were presented for the rare segregant and for reciprocal differences in segregation ratios.

Segregation ratios of "homoeologues" were close to 1:2:1 except for group 4, where no 4B homozygotes were recovered.

Mendelian segregation ratios of 3:1 were obtained as expected for a single copy hemizygous trait for all above tests.

Segregation ratios for the F2 significantly differed from ratios expected for a dominant, duplicate genetic mechanism.

Resistance in seven of the cell culture induced recombinants has been inherited via pollen according to Mendelian segregation ratios for up to eight generations.

Nine loci were polymorphic and deviation from a 1:1 segregation ratio was observed between two of three alleles at one locus (Mdh-1).

The disease segregation ratio was not significantly different from the expected segregation ratio for a single locus in an F2 generation.

Allozyme segregation ratios observed in progeny of controlled diploid crosses supported single-gene Mendelian inheritance.

Divergence of the parental genotypes is further supported by the frequency of loci with skewed allele segregation ratios.

Segregation distortion is measured by the segregation ratio k, the proportion of progeny bearing the SD chromosome.

Various segregation ratios obtained in the progenies from inter-crossings and backcrossings were explained consistently due to the possible combination of the genotypes used for the parents.

F1 backcross segregation ratios did not significantly differ from ratios expected for dominant, duplicate nuclear genes for tolerance to aluminum.

Map construction is relatively easy using a DH population derived from a hybrid of two homozygous parents as the expected segregation ratio is simple, i.e. 1:1.

In each case, the raw figures per school are converted into a segregation index and a segregation ratio (see Gorard and Fitz 1998b for further details).

There were significant deviations from expected segregation ratios at two loci, but only at one of the loci was the gene number significantly different from the F2C.

Most of the 227 AFLP fragments showed a Mendelian segregation ratio of 1:1, and all were assigned to the seven barley chromosomes.

Segregation ratio estimates for female sibships increased from those with at least one to those with at least two intersexes less than expected for polygenic inheritance.

Alleles at the locus are revealed as codominant bands on Southern blots of heterozygotes, but the segregation ratio among the F2 progeny deviated significantly from the expected 1:2:1.

The segregation ratio with gene int-a1 was also disomic but it could not be assigned to the 60% distal segment because its location on chromosome 5 is questionable at this time.

For the cross 'Virden' × 'Ellice', a single RAPD marker was obtained that did not have the expected segregation ratio but was associated with spot blotch reaction.
