What is an allele?
A type of chromosome that determines physical traits.
A variant form of a gene that can produce different traits.
A protein that helps in cell division.
A type of mutation that occurs in DNA.
What is a phenotype?
The genetic makeup of an organism.

What is a homozygous genotype?
A genotype consisting of two identical alleles for a particular gene.
A genotype consisting of two different alleles for a particular gene.
A genotype that is not expressed in the phenotype.
A genotype that results from a mutation in a single allele.
What is the role of DNA in inheritance?
DNA is responsible for the physical appearance of an organism.
DNA carries the genetic information that is passed from parents to offspring.
DNA helps in the digestion of food in living organisms.
DNA is involved in the production of energy within cells.
What is a heterozygous genotype?
A genotype consisting of two identical alleles for a particular gene.
A genotype consisting of two different alleles for a particular gene.
A genotype that does not express any traits.
A genotype that is only found in homozygous individuals.
What is a dominant trait?
A trait that is expressed in the phenotype even when only one copy of the allele is present.
A trait that is only expressed when two copies of the allele are present.
A trait that is always recessive and not expressed in the phenotype.

What is the significance of Gregor Mendel's experiments?
Mendel's experiments with pea plants established the basic principles of heredity and the laws of inheritance.
Mendel discovered the structure of DNA through his experiments with fruit flies.
Mendel's work focused on the behavior of chromosomes during cell division.
Mendel was the first to identify the role of proteins in genetic inheritance.
What is the difference between genotype and phenotype?
Genotype refers to the observable traits of an organism, while phenotype refers to the genetic makeup.
Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits.
Genotype and phenotype are the same and can be used interchangeably.
Genotype refers to the environmental influences on an organism, while phenotype refers to the genetic makeup.
