  50. Dominance vs. Recessiveness

    Mechanisms of recessive and dominant inheritance. 

    Recessive Inheritance: Both parents carry a normal gene (N), and a faulty, recessive, gene (n). The parents, although carriers, are unaffected by the faulty gene. Their offspring are affected, not affected, or carriers. This type of inheritance was first shown by Mendel.

    Dominant Inheritance: One parent has a single, faulty dominant gene (D), which overpowers its normal counterpart (d), affecting that parent. When the affected parent mates with an unaffected and non-carrier mate (dd), the offspring are either affected or not affected, but they are not carriers.
  51. Evolutionary change
    Charles Darwin knew that there was such a thing as heritable variation, but he did not know that there is such a thing as a gene, or that genes are found within DNA. However, in the twentieth century Darwinian evolutionary change and genetic change became recognized as one and the same thing. The key to understanding evolutionary change in plants and animals is to understand that it is generational change.
  52. Medelian traits
    In Mendelian inheritance, a child receiving a dominant allele from either parent will have the dominant form of the trait. Only those that received the recessive allele from both parents present with the recessive phenotype. Those that receive a dominant allele from one parent and a recessive allele from the other parent will have the dominant form of the trait. Purely Mendelian traits are a tiny minority of all traits, since most phenotypic traits exhibit incomplete dominance, codominance, and contributions from many genes.
  53. homoglogous chromosomes
    the chromosomes that make up a pair.
  54. meiosis vs. mitosis
    meiosis: form of cell division occurring in specialized tissues in the testes and ovaries that leads to the production of gametes or sex cells.

    mitosis: form of cell division whereby one-celled organisms divide and body cells divide in growth and replacement.
  55. focus of anthropology
    both biolgical and cultural characteristics and variation as well as biological and cultural evolution.
  56. sickle-cell anemia
    sickling of red blood cells, anemia, jaundice

    inheritance: dominant
  57. segregation vs. independent assortment
    segregation: in the formation of sex cells, the process in which paired hereditary factors serparate, forming sex cells contain either one of the other fact. 

    independent assortment: the inheritance patterns of differing traits are independent of one another. 

  58. heterozygote advantage.
    If a gene has more than one allele, such that members of the population with two different alleles of that gene (heterozygotes) are favored by natural selection over members of the population with two identical alleles of that gene, then we say that the gene exhibits heterozygote advantage.
  59. adaptive radiation
     process in which organisms diversify rapidly into a multitude of new forms
  60. Linnaeus

  67. buffon
