Genetics Quiz

What is an inherited trait?

• A type of asexual reproduction

• A chart that shows the likelihoods of genotypes and phenotypes

• A characteristic that is passed from parent to offspring

• The basic physical and functional unit of heredity

What is the difference between sexual and asexual reproduction?

• Sexual reproduction involves two parents, while asexual reproduction involves one

• Sexual reproduction produces identical offspring, while asexual does not

• Asexual reproduction is used by most animals, while sexual is not

• Sexual reproduction involves budding, while asexual involves binary fission

What is genetic variation?

• The process of producing offspring identical to the parent

• A type of asexual reproduction that produces two identical cells

• The occurrence of an organism, trait, or gene in more than one form within a population

• A version of a gene

What is the purpose of a Punnett Square?

• To show the process of vegetative propagation

• To display the structure of a chromosome

• To show the likelihoods of all possible genotypes and phenotypes for a trait

• To describe the basic physical and functional unit of heredity

What is an allele?

• A type of asexual reproduction

• A characteristic passed from parent to offspring

• A version of a gene

• The basic physical and functional unit of heredity

How do dominant and recessive alleles differ in genetic expression?

• Dominant alleles require two copies to be expressed, while recessive alleles only need one

• Recessive alleles mask the expression of dominant alleles

• Dominant alleles are expressed if at least one copy is present, while recessive alleles are expressed only if two copies are present

• There is no difference in how they are expressed

What role do chromosomes play in heredity?

• Chromosomes are the basic units of DNA replication

• Chromosomes carry genes, the units of heredity, from parents to offspring

• Chromosomes are involved in protein synthesis only

• Chromosomes prevent genetic disorders

What is the significance of Mendel's experiments with pea plants?

• They disproved the theory of evolution

• They showed that plants could be genetically modified

• They provided evidence for the theory of natural selection

• They established the laws of inheritance and the concept of dominant and recessive traits

A type of asexual reproduction that produces two identical cells is ____________?

• budding

• binary fission

• regeneration

• vegetative propogation

A type of asexual reproduction where the offspring grows out of the parent organism is ____________?

• budding

• binary fission

• regeneration

• vegetative propogation
