With their colorful splotches of fur, calicos are some of the most easily recognized cats. However, calico is not a breed, ...

This discovery not only reveals a communication system between parental alleles but also points to potential therapeutic strategies for diseases associated with haploinsufficient genes. Have you ever ...

Genes are located on chromosomes. Chromosomes are in pairs and genes, or their alleles, are located on each of these pairs. When the cell divides in half, each chromosome ends up in a different cell.

All eggs contain one X chromosome. Half of sperm contain one ... Only in very rare cases a female will have two recessive alleles and be a sufferer. Affects nerve cells in the brain, leading ...

Genes and alleles are essential to basic genetics, but what are the differences between them? In this guide, we compare genes and alleles and provide simple definitions and examples for both. Genes ...

As a result, the same combination of alleles is transmitted all together to the next generation. These genetic units, called “supergenes,” have so far been found in ants, butterflies ...

The ABO gene on chromosome 9 helps determine which blood type you have. You inherit two copies (alleles) of this gene — one from each parent. This gene has three possible alleles — A ...

Alleles are the parts of a chromosome that encode specific genetic traits. Just like humans, canines inherit one allele from each parent for a certain gene. But why are these called “ghost ...

However, a sizable number of genes escape inactivation in females — a phenomenon shown in this study to be reflected in height genetics and may contribute to sex differences in height. Yet dosage ...
