The reason of lower cognitive ability in subjects with the TT homozygosis can only be object of speculation, due to paucity of data in literature.
This homozygosis of markers as parent of hebao carp, showed high phenotypic value (3212.48318.6,3438430.5, 3227.11465.5 and 3332.84148.4).
In exon 12, we detected only one patient with the allele G for the Lys 365 Lys polymorphism (20-22) in homozygosis, and 7 patients plus 18 controls heterozygotes.

It would therefore be important to continuously evaluate the polymorphism degree of the strains, to avoid a marked increase of homozygosis. This would result in the expression of deleterious genes that can cause high matrix mortality.
The process caused homozygosis of recessive or deleterious genes and reduced the constitutional heterozygosity of tumor-suppressor genes, giving rise to neoplasia (LASKO et al., 1991; ZIMMERMANN, 1992; BEUMER et al., 1998).
Also, the results reflected that these populations have controlled management in order to maximize gene purity and homozygosis.
Phenotypes having a high C18:1 content carried three dominant alleles (genotype [Ol.sub.1]_[Ol.sub.2]_[Ol.sub.3]_), while the two dominant alleles [Ol.sub.1] and [Ol.sub.2] with the third gene in recessive homozygosis (genotype [Ol.sub.1]_[Ol.sub.2]_[ol.sub.3][ol.sub.3]) expressed intermediate C18:1 levels.
Another patient carried the DQ8 molecule encoded by the DQB1*0302 allele, and the remaining patient had the haplotype DQB1*0501 in homozygosis (15).
Genetic analysis showed heterozygous or homozygosis mutations in the ETFDH gene [Supplementary Table 1] [SUPPORTING:1].{Figure 1}
Homozygosis is not frequent and the question of the number of hPS cell lines that should be generated in order to cover a maximum number of individuals is critical.
