American Journal of Botany, Vol. 27, No. 8 (Oct., 1940), pp. 683-686 (4 pages) Metaphase and anaphase chromosomes of the second reduction division of Gasteria spp. hitherto considered as displaying an ...

Polyploid crops often display enhanced vigor, larger organs, and unique reproductive behaviors, making polyploidization a powerful breeding tool. A recent study identified how a single gene, ClOSD1, ...

Many tumors express meiotic genes that could potentially drive somatic chromosome instability. While germline cohesin subunits SMC1B, STAG3, and REC8 are widely expressed in many cancers, messenger ...

Researchers from the University of Arizona have unveiled that coordinated Y chromosome loss in both cancer cells and immune cells may explain the worse prognosis in people with this alteration. The ...

Somatic mosaicism is the accumulation of mutations in DNA sequence or copy number in cellular genomes after fertilization. It is a known cause of neurological disorders including developmental brain ...

A study led by researchers at NYU Grossman School of Medicine and UC San Diego Moores Cancer Center has found that patients with head and neck cancer who have more genetic material at a specific ...

To investigate how Cas9 gene editing affected T cells, the researchers targeted the first exon of the TRAC locus, which encodes the T cell receptor on chromosome 14. As expected, DNA sequencing ...

When Nettie Steven discovered the Y chromosome in 1905 while studying the mealworm Tenebrio molitor, she identified it as a sex-determining chromosome. As it turns out, the chromosome also has ...
