  • Define species?
    A group of populations whose members have the potential to interbreed and produce viable, fertile offspring that can mate with each other
  • Morphological Classification is based on?
    Observable characteristics
  • Binomial nomenclature is based on?

    Genus & species
  • Describe function of gene flow? 

    Holds the gene pools of populations together and allows them to continue to reproduce with one another
  • What occurs if a population is isolated
    • Limited gene flow
    • reproductive isolation
    • speciation
  • Define population
    a group of individuals of the same species in same area at the same time. They; rely on the same resources, interact, and interbreed
  • Compare and contrast species vs populations
    Subjective, as populations is much larger
  • Define speciation
    the process by which development of new species from pre-existing species over time
  • Changes in environment will cause migration and allow a population to move and mate to organisms in a new environment, causing a divergence of genetic/phenotypic clustering
  • Organisms with different numbers of chromosomes are unlikely to be able to interbreed successfully
  • Loci is the genetic address
  • Karyogram is a visual display of chromosomes arranged by size, shape, and banding pattern
  • Outline functions of karyogram
    • identify aneuploidic conditions
    • chromosomal abberations
  • Identify how chromosome 2 provides evidence of fusion 

    • Banding pattern matches two separate chromosomes in apes
    • Centromere location does not correlate with the humans
  • Define genome
    entire genetic material of an organism
  • Define SNPs
    Single Nucleotide Polymorphisms, idkidk
  • Pseudogenes are present and considered leftovers of once functional genes that have acquired too many insertions or deletions
  • Outline the process of transcription of pseudogenes
    Pseudogenes are transcribed into non-coding RNA thus it cannot be translated
  • Human Genome Project sequencing factories were generating DNA sequences at a rate of 1000 nucleotides per second 24/7, its a database, they were able to identify the millions of base pairs in chromosomes
  • Whole-genome sequencing (WGS) is a method for analyzing entire genomes
  • Applications of WGS
    • availability to all patients
    • infectious disease monitoring
    • cancer treatments
