1. What are traits?
a) Interactions with an individual's environment.
b) Characteristics and qualities that make us who we are.
c) Grey areas between two extremes.
d) People with brown hair and blue eyes.
2. When would a recessive trait be seen in an organism?
a) When there is one dominant and one recessive gene for the trait present in the offspring.
b) When there are two dominant genes for the trait of the present in the offspring.
c) When there are two recessive gene for the trait of the present in the offspring.
d) Never.
b) When there is one dominant and one recessive gene for the trait present in the offspring.

1. What is hereditary?
2. What do we call the shape or arrangement of a strand of DNA?
3. How many chromosomes do we have? Where do these chromosomes come from?
1. Hereditary refers to the passing of traits or characteristics from parents to offspring through genetics.
2. The shape or arrangement of a strand of DNA is called a double helix.
3. Humans typically have 46 chromosomes (23 pairs). These chromosomes come from both parents, with 23 chromosomes inherited from the mother and 23 from the father.
1. What are traits?
2. What are DNA and genes?
3. What are proteins?
4. What is inheritance?
5. What is mutation?
1. Traits are characteristics or attributes that can be observed in individuals, such as physical features, behaviors, or genetic predispositions.
2. DNA (deoxyribonucleic acid) is a hereditary material found in all living organisms. Genes are segments of DNA that contain instructions for the development and functioning of an organism.
3. Proteins are large biomolecules made up of amino acids. They play crucial roles in various biological processes, including cell structure, enzymatic reactions, and regulation of gene expression.
4. Inheritance refers to the passing of traits or genetic information from one generation to the next.
5. Mutation is a change in the DNA sequence of a gene. It can occur naturally or be induced by various factors and can lead to alterations in the genetic information, potentially resulting in new traits or diseases.
whats the purpose of a gene?
The purpose of a gene is to store the instructions for building and regulating proteins. Genes serve as the basic units of heredity and contain the information that determines an organism's traits and characteristics. They are involved in various biological processes, including development, growth, metabolism, and response to the environment. Genes play a crucial role in determining an organism's physical features, behaviors, and susceptibility to certain diseases.
