New findings of researchers from the University of Modena and Reggio Emilia (Mauro Mandrioli, Valentina Monti and Gian Carlo Manicardi) show that in aphids the two X chromosomes have a different ...

The first theoretical model of condensin, a molecular machine involved in packing and unpacking chromosomes, accurately reproduces all known experiments with just two parameters. To scrunch a ...

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within ...

The Telomere-to-Telomere (T2T) consortium, co-led by UC Santa Cruz Genomics Institute Associate Director Karen Miga and National Institutes of Health Genomics Research Institute Senior Investigator ...

A new application of the CRISPR/Cas molecular scissors promises progress in crop cultivation. Researchers have succeeded in modifying the sequence of genes on a chromosome using CRISPR/Cas. For the ...

Inheriting a normal and intact number of chromosomes in germ cells, egg and sperm, is essential for the preservation of all species. With increasing age, the risk of the egg cell not inheriting the ...

A team of biologists has uncovered a mechanism that determines faithful inheritance of short chromosomes during the reproductive process. The discovery elucidates a key aspect of inheritance -- ...

One of the fundamental rules of inheritance states that different alleles (gene copies) of a trait, such as sex, are inherited with equal frequency. "However, we have long known that there are genes ...

Two decades after the human genome sequence was completed, researchers have finally finished a map of the piece that makes males distinct. The Y chromosome is what distinguishes biological males from ...

Autosomal inheritance is when a parent passes down a condition to a child via autosomes, a type of chromosome. In autosomal inheritance, a copy of a faulty gene from one parent can cause a condition ...
