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 8
Describe Mendel’s Law of Dominance.
Describe what is meant by a monohybrid cross.
Explain the difference between dominant and recessive alleles.
Explain why Mendel’s work was not recognized until after his death.

Fill in the blank: Mendel’s experiments led to the discovery of the basic principles of _______.
Fill in the blank: The alternative forms of a gene are called _______.
Fill in the blank: The first generation of offspring from a cross is called the _______ generation.
Fill in the blank: The gene combination Tt is called _______.
True or False: A Punnett square is used to predict the outcome of genetic crosses.
True or False: All traits follow Mendelian inheritance patterns.
True or False: In Mendelian inheritance, each parent contributes one allele for each gene to their offspring.
True or False: In Mendelian inheritance, recessive traits are always masked by dominant traits in the heterozygous condition.
