• Chromosome

• Gene

• DNA

Who is known as the father of genetics?

• Charles Darwin

Explain the difference between genotype and phenotype.

• Genotype is the observable traits, while phenotype is the genetic makeup.

• Genotype is the genetic makeup, while phenotype is the physical characteristics.

• Genotype is the physical characteristics, while phenotype is the genetic makeup.

• Genotype and phenotype are the same thing.

What are inherited characteristics called?

• Behaviors

• Skills

• Habits

• Traits

How are traits passed from one generation to the next?

• By sharing food and water between parents and offspring

• Through the exchange of money between parents and offspring

• Through the passing down of knowledge and skills from parents to offspring

• Through the transmission of genes from parents to offspring during reproduction.

What is the function of DNA in the body?

• It regulates body temperature

Where are genes located in the human body?

• In the cell membrane of human cells

• In the cytoplasm of human cells

• In the mitochondria of human cells

• In the nucleus of human cells, within structures called chromosomes.

What is the role of genes in determining traits?

• Genes have no role in determining traits

• Genes are only passed down from the mother

• Genes contain the instructions for building and maintaining the body's cells and pass on traits from one generation to the next.

• Genes are only responsible for physical appearance

Explain the process of genetic inheritance.

• Offspring do not inherit any traits from their parents

• Traits are acquired through the environment and not inherited

• Traits are passed from parents to offspring through the transmission of genetic information.

• Genetic information is only passed from mother to offspring
