Mendelian Genetics Quiz

What was Gregor Mendel known as?

• Father of Genetics

• Father of Physics

• Father of Biology

• Father of Chemistry

Answer explanation

Gregor Mendel is known as the Father of Genetics for his pioneering work in the field of heredity and inheritance.

Which law states that each trait is controlled by 2 genes or alleles?

• Law of Segregation

• Law of Independent Assortment

• Law of Probability

• Law of Dominance

Answer explanation

The correct choice is the Law of Segregation, which states that each trait is controlled by 2 genes or alleles.

What is the term for plants that consistently have offspring with the same trait as the parent?

• Heterozygous plants

• True breeding plants

• Mutants

• Hybrids

Answer explanation

True breeding plants consistently have offspring with the same trait as the parent, making them the correct term for plants with this characteristic.

Which law states that alleles for different traits segregate independently during meiosis?

• Law of Probability

• Law of Dominance

• Law of Independent Assortment

• Law of Segregation

Answer explanation

The Law of Independent Assortment states that alleles for different traits segregate independently during meiosis, leading to the random assortment of genes into gametes.

What is the term for the combination of alleles present in an individual?

• Phenotype

• Genotype

• Homozygous

• Heterozygous

Answer explanation

The term for the combination of alleles present in an individual is called the genotype. It represents the genetic makeup of an organism, including both dominant and recessive alleles.

Which law explains why traits 'disappear' in one generation and reappear in another?

• Law of Dominance

• Law of Segregation

• Law of Independent Assortment

• Law of Probability

Answer explanation

The Law of Segregation explains why traits 'disappear' in one generation and reappear in another by detailing the separation of alleles during gamete formation.

What is the most common version in the general population called?

• Mutant allele

• Mutant phenotype

• Wildtype allele

• Wildtype phenotype

Answer explanation

The correct choice is 'Wildtype allele' which refers to the most common version in the general population.

Which law states that the probability of two or more events occurring simultaneously is equal to the product of their individual probabilities?

• Law of Probability

• Law of Dominance

• Law of Segregation

• Law of Independent Assortment

Answer explanation

The Law of Probability states that the probability of two or more events occurring simultaneously is equal to the product of their individual probabilities, making it the correct choice in this context.

What is the statistical analysis of genetic data called?

• Product Rule

• Test Cross

• Punnett Square

• Chi-square analysis

Answer explanation

The statistical analysis of genetic data is called Chi-square analysis, which is used to determine if there is a significant difference between the expected and observed frequencies of certain genetic traits.

Which law explains that during meiosis, each allele separates in an orderly manner from its partner?

• Law of Dominance

• Law of Independent Assortment

• Law of Probability

• Law of Segregation

Answer explanation

The Law of Segregation explains that during meiosis, each allele separates in an orderly manner from its partner.
