QUESTIONS LIST:

  • genome : complete set of genetic material in an organism, including all of its genes.
  • allele : alternative version of a gene found at the same locus on homologous chromosomes.
  • locus : specific physical location of a gene or dna sequence on a chromosome.
  • phenotype : observable characteristics of an organism resulting from genotype and environment.
  • genotype : genetic makeup of an organism for a particular trait or set of traits.
  • homozygous : having two identical alleles for a given gene.
  • heterozygous : having two different alleles for a given gene.
  • dominant : allele whose trait is expressed in the phenotype when present in a heterozygote.
  • recessive : allele whose trait is masked in the phenotype when a dominant allele is present.
  • mendel : scientist who discovered the fundamental laws of inheritance using pea plants.
  • segregation : mendel’s first law stating that alleles for a trait separate during gamete formation.
  • independent assortment : mendel’s second law stating that alleles of different genes assort independently during gamete formation.
  • monohybrid : genetic cross involving a single trait, often producing a 3:1 phenotypic ratio.
  • dihybrid : genetic cross involving two traits, often producing a 9:3:3:1 phenotypic ratio.
  • epistasis : interaction between genes where one gene masks or modifies the expression of another.
  • complementary genes : two genes that must both have a dominant allele present to produce a phenotype.
  • dominant epistasis : gene interaction where a dominant allele at one locus masks expression at another locus.
  • recessive epistasis : gene interaction where a homozygous recessive genotype at one locus masks expression at another locus.
