The results of inbreeding can be very distressing to witness. In this Instagram post, we see a captive lion with skull ...

Pure-bred dogs have been regarded as superior to crossbreeds or what some people refer to as mutts. However, we now ...

In this series, ‘Genomics 101’, we go back to basics and explore some of the most important topics in genomics. In this blog, we explain the meaning of dominant and recessive genes, and how they are ...

Genetic disorders are diseases caused by an abnormality in a gene, often described as a mutation. When such diseases are inherited (rather than resulting from a random mutation), they are passed along ...

Heterozygous genotypes can affect traits like eye and skin color where one allele may be dominant over another. Certain diseases like sickle cell anemia and cystic fibrosis can have a heterozygote ...

Populations live in rapidly changing environments – droughts come and go, food sources change, human activities reshape habitats. For scientists, this raises a fundamental puzzle: How do populations ...

Your genes code for all your traits. Some genes are dominant and expressed if you receive a copy from one parent. Others are recessive and only apparent if you receive a copy from both parents. Genes ...

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 ...

Some health problems are passed down through families. There are different ways this can happen. To have a child born with what’s called an “autosomal recessive disease” like sickle cell disease or ...
