    Genomic Imprinting and Inheritance

    Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
    The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

    Conservation of Small Populations

    Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

    Genetics of Speciation02:16

    Genetics of Speciation

    Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

    Mutation, Gene Flow, and Genetic Drift01:09

    Mutation, Gene Flow, and Genetic Drift

    In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

    Gene Flow02:39

    Gene Flow

    Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

    Genetic Drift03:33

    Genetic Drift

    Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.
