Researchers working on an incurable blood cancer can now use a new lab model that could make testing potential new treatments ...

Sex Chromosome Inheritance Sex chromosomes are the X and Y chromosomes that play a role in gender differentiation. Females inherit two X chromosomes, one from each parent. So a female can have a ...

BACKGROUND: Heterozygous pathogenic variants in the central region (exon 23–34) of FBN2 cause a hereditary connective tissue disorder named congenital contractural arachnodactyly, which presents with ...

The Y chromosome is about one-third the size of the X and contains far fewer genes. Now, scientists have found that this smaller chromosome can degrade over time. "The idea is that as men grow ...

eLife Assessment This valuable paper describes the stiffness of meiotic chromosomes in both oocytes and spermatocytes. The authors identify differences in stiffness between meiosis I and II ...

The heterozygous Punnett square is a basic mathematical grid used to plot inherited traits, such as eye color or the likelihood of sickle cell disease. As the study of molecular genetics advances, the ...

When people inherit the same gene variant from both biological parents, they have homozygous genes. Read more here and the comparisons to heterozygosity.

Heterozygous hemochromatosis does not necessarily require any treatment. However, the gene can pass to children, which will mean they carry it as well.

A novel genome editing technique, NICER, is based on the creation of multiple nicks in single DNA strands by nickase. The method can correct heterozygous mutations using two mechanisms: multiple ...

While all human chromosomes contain repeats, more than 30 million letters of the Y chromosome — out of 62.5 million — are repetitive sequences, sometimes called satellite DNA or junk DNA.

The findings, published Wednesday (Aug. 23) in the journal Nature, may make it easier to detect gene variants on the Y chromosome and link them to specific traits, as well as to develop ...
