Non-Mendelian Inheritance
Biology ⇒ Genetics and Heredity
Non-Mendelian Inheritance starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Non-Mendelian Inheritance.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A cross between a red-flowered and a white-flowered snapdragon produces all pink-flowered offspring. What type of inheritance is this?
A cross between two pink snapdragons (incomplete dominance) produces offspring in what phenotypic ratio?
A man with type AB blood and a woman with type O blood have children. What are the possible blood types of their children?
A woman with type AB blood and a man with type AB blood have a child. What is the probability that the child will have type O blood?

Codominance occurs when:
(1) Both alleles are expressed equally in the phenotype
(2) One allele is completely dominant over the other
(3) Neither allele is expressed
(4) The alleles blend to form an intermediate phenotype
In codominance, the heterozygote phenotype is:
(1) Intermediate between the two homozygotes
(2) The same as one of the homozygotes
(3) A combination where both traits are fully expressed
(4) Not expressed at all
Which of the following best describes epistasis?
(1) One gene masks the effect of another gene
(2) Both alleles are expressed equally
(3) The phenotype is a blend of two alleles
(4) Genes are located on the same chromosome
Which of the following best describes maternal inheritance?
(1) Traits inherited from both parents
(2) Traits inherited only from the mother
(3) Traits inherited only from the father
(4) Traits inherited from grandparents
A woman with blood type A and a man with blood type B have a child with blood type AB. This is an example of ________.
Fill in the blank: In ________ inheritance, more than two alleles exist for a single gene locus within a population.
Fill in the blank: The inheritance of traits controlled by genes located in the chloroplast is called ________ inheritance.
Fill in the blank: The inheritance of traits determined by genes located on the sex chromosomes is called ________ inheritance.
True or False: All non-Mendelian inheritance patterns involve more than two alleles.
True or False: All traits that do not follow Mendel's laws are considered non-Mendelian.
True or False: In codominance, the phenotype of the heterozygote is a blend of the two homozygotes.
True or False: In non-Mendelian inheritance, all traits follow the law of independent assortment.
