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.
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?
If a plant with genotype YYRR is crossed with a plant with genotype yyrr, what will be the genotype of all F1 offspring?
Mendel’s law of independent assortment applies to genes located on: (1) The same chromosome (2) Different chromosomes (3) Mitochondrial DNA (4) Only sex chromosomes
Mendel’s law of segregation states that: (1) Alleles separate during gamete formation (2) Alleles blend together in offspring (3) Only dominant alleles are inherited (4) Genes are linked together
Which of the following best describes a test cross? (1) Crossing two homozygous individuals (2) Crossing an individual with a dominant phenotype with a homozygous recessive individual (3) Crossing two heterozygous individuals (4) Crossing two individuals with the same phenotype
Which of the following best describes Mendel’s experimental approach? (1) He used statistical analysis (2) He observed one trait at a time (3) He kept detailed records (4) All of the above
The alternative forms of a gene are called ________.
The observable characteristics of an organism are known as its ________.
The physical expression of a trait is called the ________.
True or False: In Mendelian inheritance, each parent contributes one allele for each gene to their offspring.
True or False: Incomplete dominance is an example of non-Mendelian inheritance.
True or False: Mendel’s experiments were conducted on pea plants.
True or False: Mendel’s laws apply to all genes, regardless of their location on the chromosome.
