5.4 Non-Mendelian Genetics

Cards (24)

  • Incomplete dominance results in a heterozygous phenotype that is a blend of homozygous traits.
    True
  • Incomplete dominance occurs when neither allele is dominant
  • Match the human blood type genotype with its corresponding phenotype:
    AA ↔️ Type A
    BB ↔️ Type B
    AB ↔️ Type AB
    OO ↔️ Type O
  • In human blood types, the O allele is recessive.
    True
  • What does Non-Mendelian Genetics refer to?
    Inheritance patterns beyond Mendel's laws
  • In snapdragons, what phenotype results from the heterozygous genotype (RW)?
    Pink
  • Codominance occurs when both alleles in a heterozygous genotype are fully expressed
  • What does the term "Multiple Alleles" refer to?
    More than two allele forms for a single gene
  • Polygenic inheritance leads to continuous variation in phenotypes.

    True
  • Epistasis occurs when one gene masks or modifies the expression of another gene
  • Where are sex-linked genes located?
    Sex chromosomes
  • If a colorblind male mates with a carrier female, 50% of their sons will be colorblind.

    True
  • Non-Mendelian genetics refers to inheritance patterns that do not follow Mendel's laws of segregation
  • What phenotype does the heterozygous genotype (RW) produce in snapdragons under incomplete dominance?
    Pink
  • Codominance results in a heterozygous phenotype where both alleles are fully expressed.

    True
  • Multiple alleles refer to the existence of more than two allele forms for a single gene
  • What phenotype does the genotype AO produce in human blood types?
    Type A
  • Incomplete dominance occurs when neither allele is dominant
  • Incomplete dominance results in a phenotype that is a blend of two homozygous phenotypes.
    True
  • Match the human blood type genotype with its phenotype and antigens on red blood cells:
    AA ↔️ Type A, A
    BB ↔️ Type B, B
    AB ↔️ Type AB, A and B
    OO ↔️ Type O, None
  • In human blood types, the A and B alleles are codominant
  • What are examples of polygenic traits in humans?
    Height, skin color, eye color
  • In epistasis, a regulatory gene controls the function of a structural gene.

    True
  • X-linked traits are more prevalent in males
