  2. Genetic distance - Wikipedia

    en.wikipedia.org/wiki/Genetic_distance

    By examining the differences between allele frequencies between the populations and computing genetic distance, we can estimate how long ago the two populations were separated. [ 7 ] Let’s suppose a sequence of DNA or a hypothetical gene that has mutation rate of one base per 10 million years.

  3. Human genetic variation - Wikipedia

    en.wikipedia.org/wiki/Human_genetic_variation

    A graphical representation of the typical human karyotype The human mitochondrial DNA. Human genetic variation is the genetic differences in and among populations. There may be multiple variants of any given gene in the human population , a situation called polymorphism. No two humans are genetically identical.

  4. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    Indeed, even within humans, there has been found to be a previously unappreciated amount of copy number variation (CNV) which can make up as much as 5–15% of the human genome. In other words, between humans, there could be +/- 500,000,000 base pairs of DNA, some being active genes, others inactivated, or active at different levels.

    BI GRAPHICS_percentage of DNA humans share with other things_humans A 2005 study found that chimpanzees -- our closest living evolutionary relatives -- are 96 percent genetically similar to humans.

  6. Genetic linkage - Wikipedia

    en.wikipedia.org/wiki/Genetic_linkage

    Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart.

  7. Isolation by distance - Wikipedia

    en.wikipedia.org/wiki/Isolation_by_distance

    The bottom chart measures the genetic distance between all pairs of populations according to the Fst statistic. Populations separated by greater distance are more dissimilar than those that are geographically close. Isolation by distance (IBD) is a term used to refer to the accrual of local genetic variation under geographically limited ...

  8. Nucleic acid sequence - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_sequence

    The DNA in an organism's genome can be analyzed to diagnose vulnerabilities to inherited diseases, and can also be used to determine a child's paternity (genetic father) or a person's ancestry. Normally, every person carries two variations of every gene , one inherited from their mother, the other inherited from their father.

  9. Human evolutionary genetics - Wikipedia

    en.wikipedia.org/wiki/Human_evolutionary_genetics

    Even if we can't tell absolute divergence times exactly, we can be pretty sure that the divergence time between chimpanzees and humans is about sixfold shorter than between chimpanzees (or humans) and monkeys. One study (Takahata et al., 1995) used 15 DNA sequences from different regions of the genome from human and chimpanzee and 7 DNA ...
