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 12
A heterozygous tall pea plant (Tt) is crossed with a homozygous short plant (tt). What percentage of the offspring will be tall?
A pea plant with genotype Aa is self-pollinated. What is the probability that an offspring will be homozygous recessive?
A plant with genotype RrYy is crossed with another plant with the same genotype. What fraction of the offspring will have the genotype rryy?
Define the term 'allele'.
Describe the difference between monohybrid and dihybrid crosses.
Explain Mendel’s law of dominance.
Explain the difference between genotype and phenotype.
Explain why Mendel’s law of independent assortment does not always apply to genes located close together on the same chromosome.
If a pea plant with genotype Tt is crossed with another Tt plant, what is the probability of obtaining a short (tt) offspring?
If a plant with genotype YYRR is crossed with a plant with genotype yyrr, what will be the genotype of all F1 offspring?
If a trait is controlled by a single gene with two alleles, and one allele is completely dominant over the other, what is the expected phenotypic ratio in the F2 generation from two heterozygous parents?
In a cross between a homozygous dominant and a homozygous recessive individual, what will be the genotype of all F1 offspring?
In a dihybrid cross, what is the probability of obtaining an offspring with both dominant phenotypes if both parents are heterozygous for both traits?
What is meant by the term 'true-breeding' in Mendelian genetics?
What is the expected genotypic ratio in the F2 generation of a monohybrid cross?
What is the genotype ratio expected in the F2 generation of a monohybrid cross between two heterozygous parents?
What is the main reason Mendel’s work was not recognized during his lifetime?
What is the phenotypic ratio in the F2 generation of a dihybrid cross according to Mendel’s law?
What is the purpose of a test cross in Mendelian genetics?
Who is known as the father of genetics?
