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 ...

Duchenne muscular dystrophy (DMD) occurs as a result of genetic changes on the X chromosome. If someone has a gene change that can cause DMD, their children may inherit that change. DMD is a ...

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 ...

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 ...

Mitotic chromosomes are pivotal for the inheritance of genetic material. Now, it is already known that chromosomes vary in dimensions among organisms. But what governs mitotic chromosomal size and ...

Small plastic or metal bits at the end of shoelaces, known as aglets, prevent laces from unraveling and protect them from wear and tear. Similarly, chromosomes are capped by telomeres—specialized ...

Some genes just don’t play fair. Researchers have uncovered a ‘selfish’ X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs. “Researchers have ...

Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...

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 ...

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically male ...
