Polytene chromosome map and inversion polymorphism in Drosophila mediopunctata

Memorias do Instituto Oswaldo Cruz, 2002
Drosophila mediopunctata belongs to the tripunctata group, and is one of the commonest Drosophila species collected in some places in Brazil, especially in the winter. A standard map of the polytene chromosomes is presented.

Cytogenetic Identification and Molecular Marker Analysis of Two Wheat–Thinopyrum ponticum Translocations with Stripe Rust Resistance

Plants
Stripe rust, induced by Puccinia striiformis f. sp. tritici (Pst), is one of the most destructive fungal diseases of wheat worldwide. Thinopyrum ponticum, a significant wild relative for wheat improvement, exhibits innate immunity to this disease.

Exploring the Effects of Robertsonian Translocation 1/29 (Rob (1;29)) on Genetic Diversity in Minor Breeds of Spanish Berrenda Cattle via Genome-Wide Analysis

Animals
Most of the previous studies on the genetic variability in Spanish “Berrenda” breeds have been carried out using DNA microsatellites. The present work aimed to estimate the genetic diversity, population structure, and potential genetic differences among ...

Chromosomal Analysis of Couples with Repeated Spontaneous Abortions in Northeastern Iran [PDF]

International Journal of Fertility and Sterility, 2015
Background Cytogenetic study of reproductive wastage is an important aspect in determining the genetic background of early embryogenesis. Approximately 15 to 20% of all pregnancies in humans are terminated as recurrent spontaneous abortions (RSAs).

Cytogenetic analysis for research and services [PDF]

Journal of thee Medical Sciences (Berkala Ilmu Kedokteran), 2016
AbstractThat the correct chromosome number in man is 46 was first recognized by Tjio and Levan in 1956. Perhaps few Indonesians know that Tjio was an Indonesian scientist studying in Sweden and then living in the US. Cytogenetic analyses are commonly performed to determine both structural and numerical chromosome aberration, whilst changes in ...
