Furthermore, artificial selection will also contribute to accumulation deleterious mutations due to the increased rate of inbreeding among these animals. The process of domestication, founder population size, and artificial selection differ between cattle breeds, which could lead to a variation in their ...
SNP (single nucleotide polymorphisms) genotype data are increasingly available in cattle populations and, among other things, can be used to predict carriers of specific mutations. It is therefore convenient to have a practical statistical method for the accurate classification of individuals into carrier...
Mutations that make males harm parthenogenetic females worse than sexual ones, however, can be seen as evolutionary spite. The spiteful trait is not the production of costly sons, but the production of males that discriminate against parthenogenetic females. Spiteful behaviour can be positively ...
In worms with mutations in two genes that regulate the UPRER(ire-1andxbp-1), the response was not activated by 1-undecene, showing that this cellular signaling pathway was essential to the activation of UPRERby the substance. Other experiments confirmed this result. Another group of mutant ne...

A "silent" mutation is not supposed to have any effect. Find out why this assumption is wrong. In fact, there are many ways a silent mutation, aka a synonymous mutation, can be harmful to an organism. Harmful mutations are not always obvious.
Many of the most harmful ocean pollutants are not the ones we can see, but instead are the ones that leach(渗人) into 4 marine ecosystem(海洋生态系统), 5 (cause) diseases and mutations(变异), not only in the marine life but in the humans and animals that consume 6(they). Some of ...
Males that face tougher competition for females risk having offspring with a greater number of harmful mutations in their genome than males without rivals. Researchers at Uppsala University have discovered this correlation in the beetle species Callosobr

Induction of genetic mutationsIn DBD treatment, physical and chemical elements like heat, charged particles, UV radiation, and reactive oxygen species (ROS) may interact with a biological system that has been exposed to radiation and result in DNA chain breaks or genomic alterations.[107] ...
