9:4:3 Complete dominance at both gene pairs; however, when one gene is homozygous recessive, it hides the phenotype of the other gene Recessive epistasis 9:7 Complete dominance at both gene pairs ...
At least three mechanisms can allow natural selection to preserve a duplicate gene pair: neofunctionalization, subfunctionalization and selection for gene dosage. Strikingly, all three of the ...
Our genome contains 3.2 billion base-pairs. A gene is typically a few-thousand base-pair-long segment of a DNA. When a gene is ‘expressed’, it means a cell will transcribe the underlying base ...
Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don’t ...
