which best describes genetic mutations
Population genetics - Wikipedia
With the fate of each neutral mutation left to chance (genetic drift), the direction of evolutionary change is driven by which mutations occur, and so cannot be captured by models of change in the frequency of (existing) alleles alone.[13][15] The origin-fixation view of population genetics generalizes this approach beyond strictly neutral mutations, and sees the rate at which a particular change happens as the product of the mutation rate and the fixation probability.[13] Four processes[edit] Selection[edit] Natural selection, which includes sexual selection, is the fact that some traits make it more likely for an organism to survive and reproduce.

The roles of ribosomes, tRNA and ATP. Students should be able to: relate the base sequence of nucleic acids to the amino acid sequence of polypeptides, when provided with suitable data about the genetic code interpret data from experimental work investigating the role of nucleic acids. Students will not be required to recall in written papers specific codons and the amino acids for which they code. Genetic diversity can arise as a result of mutation or during meiosis Content Opportunities for skills development Gene mutations involve…
What is a mutation? – YourGenome
Often cells can recognise any potentially mutation-causing damage and repair it before it becomes a fixed mutation. Mutations contribute to genetic variation within species. Mutations can also be inherited, particularly if they have a positive effect.

Specifically, the focused on the fact that 15 per cent of couples trying to have a baby are infertile, which suggested that genetic mutations that impair fertility are widespread. This was perplexing to the researchers, because common sense says that these mutations, which affect the survival of the species by reducing the number of offspring, should have been eliminated by natural selection - a key mechanism of evolution that changes the traits that are inherited by a population via random genetic mutations.
Genetics in fiction - Wikipedia
Few films have informed audiences about genetic engineering as such, with the exception of the 1978 The Boys from Brazil and the 1993 Jurassic Park, both of which made use of a lesson, a demonstration, and a clip of scientific film.[11][24] In 1982, Frank Herbert's novel The White Plague described the deliberate use of genetic engineering to create a pathogen which specifically killed women.[16] Another of Herbert's creations, the Dune series of novels, starting with Dune in 1965, emphasises genetics.

Xq28 - Wikipedia
Studies of the X chromosome as well as the entire human genome have linked Xq28 to the heredity of homosexuality in human males. Xq28 is a chromosome band and genetic marker situated at the tip of the X chromosome which has been studied since at least 1980.[1] The band contains three distinct regions, totaling about 8 Mbp of genetic information.[2] The marker came to the public eye in 1993 when studies by Dean Hamer and others indicated a link between the Xq28 marker and male sexual orientation.[3] Contents 1 Initial linkage 1.1 Controversy 2 Subsequent studies 3 Other contents 4 See also 5 Notes 6 References 7 External links Initial linkage[edit] The 1993 study by Hamer et al. examined 114 families of gay men in the United States and found…
Why Darwinism Is False | Discovery Institute
According to the modern version of Darwinism that Coyne defends, DNA carries a genetic program that encodes proteins that direct embryo development; mutations occasionally alter the genetic program to produce new proteins (or change their locations); and natural selection then sorts those mutations to produce evolution.

Atypical teratoid rhabdoid tumor - Wikipedia
However, some reports exist of AT/RTs presenting in two members of the same family, or one family member with an AT/RT and another with a renal rhabdoid tumor or other CNS tumor. These are suspected to arise from germline genetic mutations in a parent shared by affected siblings. A three-generation family is known in which two half-brothers were diagnosed with CNS atypical teratoid/rhabdoid tumors (AT/RT).
Lactose intolerance - Wikipedia
Causes[edit] Lactose intolerance is a consequence of lactase deficiency, which may be genetic (primary hypolactasia and primary congenital alactasia) or environmentally induced (secondary or acquired hypolactasia).
