false... its likely to occur in small population
Actually, genetic drift is a random process that leads to the change in frequency of certain traits in a population over time. It is not based on the fitness or survival advantage of specific traits, unlike natural selection.
Yes, genetic drift has played a role in shaping the diversity and evolution of humans. It has influenced the genetic variation within different human populations over time. In small or isolated populations, genetic drift can have a larger impact on diversity due to random changes in allele frequencies.
False. The inner core of the Earth is composed of solid iron and nickel, while genetic material is found in the nucleus of cells.
False. Scientists recognize that speciation can occur gradually over long periods of time (allopatric speciation) or more rapidly through processes like genetic drift, natural selection, and hybridization (sympatric speciation). The pace of speciation can vary depending on environmental conditions and other factors.

False. Random mating itself does not lead to microevolution; it typically maintains genetic variation within a population. Microevolution occurs due to factors such as natural selection, genetic drift, mutation, and gene flow, which can change allele frequencies over time. Random mating helps ensure that these processes can occur without the influence of selective mating patterns.

true
False. The zygote gets half of its genetic material from each parent.
False. Elderly are more likely to report their pain to a nurse.
False. Individuals of species that reproduce sexually tend to have more variation because each offspring inherits a unique combination of genes from both parents, leading to genetic diversity within the population.
