Questions and Answers
Why is sexual reproduction more likely to produce variations in offspring compared to asexual reproduction?
Why is sexual reproduction more likely to produce variations in offspring compared to asexual reproduction?
- Asexual reproduction leads to more DNA mutations during replication.
- Asexual reproduction combines genetic material from two parents.
- Sexual reproduction allows for the combination of genes from two parents. (correct)
- Sexual reproduction involves a single parent, preserving genetic information.
Which of the following best describes 'inheritance' in the context of genetics?
Which of the following best describes 'inheritance' in the context of genetics?
- The process through which characteristics pass from one generation to another. (correct)
- The process by which traits are modified during an organism's life.
- The process of traits disappearing in offspring.
- The process of traits remaining constant within a single generation.
If a person is born with a specific genetic condition, which statement best describes this trait?
If a person is born with a specific genetic condition, which statement best describes this trait?
- It is acquired through interactions with other individuals.
- It is likely an inherited trait, present since birth. (correct)
- It is a result of lifestyle choices made by the person.
- It is solely a result of environmental factors during development.

Study Notes
- Heredity and Variation is the topic
Inheritance
- Inheritance is the process through which characters pass from one generation to another
Heredity
- Heredity is the transfer of characters from parents to offspring
Variations
- Variations are more common in sexual offspring compared to asexual offspring
Inherited Traits
- Traits expression tells how specific characteristics or features known as traits are displayed in an organism
- These include physical appearance
Inherited Traits
- Traits are present in an individual since birth
- Traits are the result of changes in DNA
- Examples include color of eyes, skin, hair, height
Genes
- Genes are a segment of DNA that contain information for the synthesis of a particular protein
- A gene is a functional unit of DNA
- Genes are present on the chromosomes of the nucleus
- A gene is a piece of DNA that codes for one polynucleotide (protein)
- A gene controls the structure and function of a cell and stores protein synthesis information
DNA Chromosomes
- DNA Chromosomes are thread-like structures in the nucleus of a cell
