The phrase "a lack of segregation" is correct and usable in written English.
It can be used to describe a situation where there is no separation or division between different groups or categories.
Example: "The study revealed a lack of segregation in the educational system, leading to diverse classrooms with students from various backgrounds."
Alternatives: "absence of separation" or "insufficient division".
Furthermore, at full time at the Stade Vélodrome a lack of segregation in the stands appeared to allow Russian supporters to charge their English counterparts.
A lack of segregation was the major problem, along with the fact that an estimated 600 Villa fans had travelled without tickets, leading to the riot that saw 27 arrested and 20 injured.
Sadly, and partly due to a lack of segregation, that led to clashes between a small group of fans from each club before kick-off and the involvement of riot police.
The high SNP false negative rate of 20.5% (loci with >10× coverage) compared to dbSNP is most probably due to a combination of a lack of segregation of these SNPs in HF cattle and inaccurate dbSNP data.
With specific regard to hereditary hearing loss, the analysis of several families has revealed a lack of segregation of a given allele with the clinical status (i.e. carriers who are in some cases healthy in others affected).
An additional important observation was a lack of perfect segregation of these rare variants with affection status in families (Bucan et al, 2009).
This deviation from independence can have different causes, such as a lack of independent segregation or recombination, or any number of other evolutionary forces.
This finding could, however, also be explained by a lack of power in the segregation analyses in this pedigree since it contains a large number of founder alleles with rather few observations for each inherited allele.
On the other hand, lack of segregation of a variant with a phenotype provides strong evidence against pathogenicity.
p.Met34Thr was then re-classified as a polymorphism on the basis of contrasting functional data and lack of segregation with a hearing phenotype in some families (28).
The lack of segregation with a hearing phenotype in some trios and large families prompted its classification as a polymorphism (17), and as such, it is currently listed in online databases (e.g. http://web.expasy.org/variant_pages/VAR_009968.html).org/variant_pages/VAR_009968.html
