Genetic Variability

What is a mutation?

• A mutation is a change in the DNA sequence of an organism.

• A mutation is a type of plant

• A mutation is a weather phenomenon

• A mutation is a type of food

Explain the difference between asexual and sexual reproduction.

• In asexual reproduction, offspring inherit genetic material from both parents resulting in genetic diversity.

• Sexual reproduction results in genetically identical offspring to the parent.

• Asexual reproduction involves the fusion of gametes from two parents.

• In asexual reproduction, offspring are genetically identical to the parent, while in sexual reproduction, offspring inherit genetic material from both parents resulting in genetic diversity.

How do mutations contribute to genetic variability?

• Mutations contribute to genetic variability by preventing any changes in the DNA sequence.

• Mutations contribute to genetic variability by reducing the number of alleles.

• Mutations contribute to genetic variability by stabilizing the DNA sequence.

• Mutations contribute to genetic variability by introducing new alleles through changes in the DNA sequence.

Provide an example of a mutation that can be beneficial to an organism.

• Extra fingers mutation providing enhanced dexterity

• Sickle cell mutation providing resistance to malaria

• Blue eye mutation increasing attractiveness

• Fast metabolism mutation causing obesity

Describe the process of asexual reproduction.

• Asexual reproduction involves two parent organisms.

• Asexual reproduction results in genetically diverse offspring.

• Asexual reproduction only occurs in plants.

• Asexual reproduction involves a single parent organism that produces offspring genetically identical to itself through methods such as binary fission, budding, or spore formation.

What are the advantages of sexual reproduction over asexual reproduction?

• Decreased genetic diversity

• Increased energy consumption

• Lower reproductive success

• Genetic diversity, adaptability, resistance to diseases, DNA repair, elimination of harmful mutations

How do offspring inherit traits in sexual reproduction?

• Offspring inherit traits in sexual reproduction through the combination of genetic material from both parents.

• Offspring inherit traits in sexual reproduction through environmental factors alone.

• Offspring inherit traits in sexual reproduction through a single parent only.

• Offspring inherit traits in sexual reproduction through random chance.

What are some disadvantages of mutations?

• Some disadvantages of mutations include genetic disorders, reduced fitness, harmful traits, and disruption of normal biological processes.

• Improved genetic stability

• Enhanced biological processes

• Increased fitness

Compare and contrast the genetic variability in asexual and sexual reproduction.

• Genetic variability is not affected by the type of reproduction.

• Genetic variability is low in asexual reproduction and high in sexual reproduction.

• Genetic variability is high in asexual reproduction and low in sexual reproduction.

• Asexual reproduction leads to more genetic diversity than sexual reproduction.

Why is genetic variability important for the survival of a species?

• Genetic variability causes extinction

• Genetic variability reduces species diversity

• Genetic variability allows for adaptation, increases survival chances, and prevents genetic disorders.

• Genetic variability leads to inbreeding depression
