Biology Chapter 9 Vocab Review

  1. The alleles of a particular gene are different
    heterozygous
  2. the two alleles for a trait separate when gametes are formed
    law of segregation
  3. the alleles of different genes separate independently of one another during gamete formation
    law of independent assortment
  4. not expressed when the dominant form of the trait is present
    recessive
  5. passing of traits from parents to offspring
    heredity
  6. all the offspring display only one form of a particular trait
    true-breeding
  7. factor that masks another form of a trait
    dominant
  8. first two individuals crossed in a breeding experiment
    P generation
  9. physical apperance of an organism
    phenotype
  10. a cross that considers one pair of contrasting traits
    monohybrid
  11. offspring of the F1 generation
    F2 generation
  12. when the two allels of a particular gene are the same
    homozygous
  13. branch of biology that studies heredity
    genetics
  14. different versions of a gene
    alleles
  15. offspring of the P generation
    F1 generation
  16. set of allels that an individual has
    genotype
  17. a cross that considers two pairs of contrasting traits
    dihybrid cross
  18. genetically determined variant of a characteristic
    trait
  19. diagram that predicts the outcomes of a genetic cross
    Pennett square
  20. cross of a homozygous recessive individual with an individual with a dmoninant phenotype of unknown genotype
    test cross
  21. the likelihood that a specific event will occur
    probability
  22. fraction of genotypes that appear in offspring
    genotypic ratio
  23. when heterozygous plants and homozygous dominant plants have the same phenotype
    complete dominance
  24. when pollen is transferred to a stigma from the smae plant
    self-pollination
  25. when an individual displays a trait that is intermediat between the two parents
    Incomplete dominance
  26. when both alleles for a trait are expressed in a heterozygous individual
    Codominance
  27. fraction of phenotypes that appear in offspring
    phenotypic ratio
  28. occurs between flowers of two different plants
    cross-pollination
  29. study of the structure and function of chromosomes and genes
    molecular genetics
  30. when pollen grains are transferred to the stigma
    pollination
