As with duplications, deletions can affect gene dosage and thus the resulting phenotype. Also, the larger the deletion, the more genes are likely to be involved, and the more drastic the resulting ...

(A) Genes can have unequal rates of evolution. (B) Gene loss and gene duplication are common. (C) Gene flow can occur between lineages after their separation. (D) Recombination between neighboring ...

Gene duplication is very important for the evolution of species because it can facilitate the creation of new genes. Normally, changes to genes result in loss of function and so are weeded out by ...

Large and rare duplications and deletions in a chromosome ... meaning it can be inherited from just one parent—of many gene mutations. The condition can lead to complications as severe as ...

This “partial de novo” origination bridges the gap between traditional models of gene duplication and the emergence of entirely new genes. The study also introduced new conceptual models to ...

In 1970, Japanese-American biologist Susumu Ohno proposed that the main source of new genes is gene duplication. When the body’s genome has two copies of the same gene, one copy can continue ...

As creosote grew to dominate the landscape, natural selection drove a detox-gene duplication bonanza, resulting in massive increases in the numbers of genes that produce enzymes that eliminate ...
