  • Punnett Square
  • HEREDITY
  • CODOMINANCE
  • ALLELE
the likelihood that a particular event will occurIn a genetic cross, the allele that each parent will pass on to it's offspring is based on probability
  • PUREBRED
  • MEIOSIS
  • PROBABILITY
  • HEREDITY
Genetic makeup, or allele combinations
  • PHENOTYPE
  • GENE

  • GENOTYPE
when an organism has two identical alleles for a trait
  • HOMOZYGOUS
  • HETEROZYGOUS
  • DOMINANT ALLELE
  • HYBRID
An organism's traits are controlled by the alleles it inherits from it's parents. Some alleles are dominant, while other alleles are recessive.
  • MEIOSIS
  • What were the results of Mendel's experiments, or crosses?
  • What controls the inheritance of traits in organisms?
  • If an allele is represented by a capital letter, what does this indicate?
the different forms of a gene for each variation of a trait of an organism
  • GENE
  • HEREDITY
  • ALLELE
  • TRAIT
type of cell division where one body cell produces four gametes each containing half the number of chromosomes as a parents body cell
  • ALLELE
  • MEIOSIS
  • HEREDITY
  • GENETICS
a purebred organism is the offspring of many generations that have the same traiti.e. purebred short pea plants always come from short parent plants
  • HOMOZYGOUS
  • HETEROZYGOUS
  • PUREBRED
  • HYBRID
a hybrid organism has two different alleles for a trait
  • HETEROZYGOUS
  • HYBRID
  • HOMOZYGOUS
  • PUREBRED
Mendel reasoned that individual factors, or sets of genetic information, must control the inheritance of traits in peas.The factors that control each trait exist in pairs.The female parent contributes one factor, while the male parent contributes the other factor.One factor in a pair can mask, or hide, the other factor.
  • HEREDITY
  • What controls the inheritance of traits in organisms?
  • What were the results of Mendel's experiments, or crosses?
  • If an allele is represented by a capital letter, what does this indicate?
the passing of characteristics from parents to offspring
