Mendelian Inheritance
Biology ⇒ Genetics and Heredity
Mendelian Inheritance starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in 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 10
Describe the difference between genotype and phenotype.
Describe the purpose of a Punnett square in Mendelian genetics.
Explain the significance of Mendel’s Law of Segregation in genetics.
What is a test cross used for in genetics?
Mendel’s Law of Segregation states that:
(1) Each organism carries two alleles for each trait, which separate during gamete formation
(2) Alleles for different traits assort independently
(3) Dominant alleles always mask recessive alleles
(4) Traits blend together in offspring
Which of the following best describes a dihybrid cross?
(1) A cross involving one trait
(2) A cross involving two traits
(3) A cross involving three traits
(4) A cross involving four traits
Which of the following best describes Mendel’s Law of Independent Assortment?
(1) Alleles for different traits are inherited together
(2) Alleles for different traits separate independently during gamete formation
(3) Only dominant alleles are inherited
(4) Traits are blended in offspring
Which of the following best explains why Mendel’s work was not recognized until after his death?
(1) He published in a little-known journal
(2) His results were not accurate
(3) He did not use scientific methods
(4) He only studied animals
Which of the following is a heterozygous genotype?
(1) AA
(2) aa
(3) Aa
(4) aA
Which of the following is an example of a homozygous recessive genotype?
(1) AA
(2) Aa
(3) aa
(4) aA
Which of the following is an example of a phenotype?
(1) TT
(2) Tt
(3) Tall
(4) tt
Which of the following is NOT a reason Mendel chose pea plants for his experiments?
(1) They have easily observable traits
(2) They can self-pollinate
(3) They have a long generation time
(4) They produce many offspring
Fill in the blank: In Mendel’s experiments, the trait that disappeared in the F1 generation but reappeared in the F2 generation is called __________.
Fill in the blank: The alternative forms of a gene are called __________.
Fill in the blank: The cross between an individual with an unknown genotype and a homozygous recessive individual is called a __________.
Fill in the blank: The first generation of offspring from a cross is called the __________ generation.
True or False: A monohybrid cross involves only one trait.
True or False: In Mendelian inheritance, a heterozygous individual will always show the dominant phenotype.
True or False: In Mendelian inheritance, alleles segregate during the formation of gametes.
True or False: In Mendelian inheritance, each parent contributes one allele for each gene to their offspring.
