Karyotype polymorphism in indigeneous goats from two Zambian provinces
… goats in these two provinces revealed similar karyotypes, indicating that they are likely to be related. There were no aberrations observed. Due to small sample size, this study is not a definitive study; therefore, further research should be conducted to verify the chromatin band resemblances …

The effects of chromosome number changes on mitotic fidelity and karyotype stability
The correct number of chromosomes is important for the maintenance of healthy cells and organisms. Maintenance of a correct chromosome number depends on the accurate distribution of chromosomes to the daughter cells during cell division, and errors in chromosome segregation result in abnormal …

The relationship of time of year, geographic location, insecticide exposure and the genotype of red and green morphs of the tobacco aphid, myzus nicotianae Blackman, in Virginia
… in Virginia in 1988 and 1989. Color morph and karyotype were found to be highly related. The translocated karyotype was associated with the red morphs and the normal karyotype was associated with the green morphs. The karyotype of red and green morphs did not change markedly from the beginning …

Global and chromosome-specific consequences of aneuploidy in Saccharomyces cerevisiae
Aneuploidy, an unbalanced karyotype in which one or more chromosomes are present in excess or reduced copy number, causes an array of known cellular phenotypes including proteotoxicity, genomic instability and slowed proliferation. Organisms with constitutional genomic imbalance are less fit than …

Cytogenetic and Molecular Cytogenetic Markers in Patients with Multiple Myeloma - Prognostic Significance // Цитогенетични и молекулярно-цитогенетични маркери при пациенти с множествен миелом – прогностично значение
… Of the 83 successfully performed analyses, the karyotype was normal in 69 and aberrant in 14. Depending on the chromosome set, two groups of patients with an aberrant karyotype were identified: 5 patients with a hyperdiploid karyotype and eight patients with a non-hyperdiploid karyotype. Apart …

Current Genetic Counseling Practice Following Positive Non-Invasive Prenatal Testing For Sex Chromosome Abnormalities
… but the percent consistently offering maternal karyotype (22-52%) and postnatal evaluation (28-87%) varied. Maternal karyotype was offered more often when NIPT was positive for 45,X or 47,XXX and patients had normal diagnostic testing (p72%) but the percent offering maternal karyotype (6-46%) …

Contribuição à citotaxonomia dos Scorpaeniformes (Osteichthyes - Teleostei): estudos citogenéticos em espécies do litoral do Rio de Janeiro, Brasil
… the cytotaxonomy and phylogeny of the order. The karyotypes of the Scorpaenidae species analyzed in this study confirm the great chromosome diversity found in the family in previous studies. Thus far, the karyotype of P. punctatus is unique in the arder and is hypothesized to have been originated …

Sex And Heterochromatin: An Investigation Of Sexual Dimorphism In Drosophila Melanogaster
… either the sex determination pathway, or direct karyotype sensing, could act as a signal. To determine the signal, I conducted targeted genetic screens using a reporter that responds differently to the loss of roX RNAs in males and females. I found that heterochromatic sex is independent of the …
