Shift and adapt: the costs and benefits of karyotype variations.
Variation is the spice of life or, in the case of evolution, variation is the necessary material on which selection can act to enable adaptation. Karyotypic variation in ploidy (the number of homologous chromosome sets) and aneuploidy (imbalance in the number of chromosomes) are fundamentally different than other types of genomic variants. Karyotypic variation emerges through different molecula...
متن کاملEffects of Karyotype Variations on Phenotype of Patients with Turner Syndrome
Background: Turner syndrome (TS) is a sporadic disorder caused by the absence of all or some parts one X-chromosome with major developmental consequences such as short stature and ovarian failure etc. The minor manifestations of TS are cubitus valgus, micrognatism, high-arched palate, short and/or webbed neck, hypothyroidism, etc. Different karyotype abnormalities may lead to different clinical...
متن کاملVariations on a theme: Karyotype comparison in Eurasian Myotis species and implications for phylogeny
The phylogenetic relationships within the large genus Myotis are still unsolved to a high degree although several morphological and molecular studies have been undertaken recently. In cytogenetic respect, Myotis is a very homogeneous genus as nearly all species show a karyotype with 44 chromosomes. Application of banding techniques in 17 Eurasian Myotis taxa revealed complete conservation of ch...

متن کاملKaryotype of Hairless Guinea pig
Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...
