Explore the fundamentals of the genetic theory in biology, including how traits are inherited through genes.

264 views

The genetic theory in biology explains that traits and characteristics are inherited through genes. Genes, made of DNA, are the basic units of heredity, passed from parents to offspring. They codify proteins that contribute to the structure, function, and regulation of the body's cells, tissues, and organs. Genetic variations and mutations can lead to different physical attributes or predispositions to certain diseases, explaining diversity and inheritance patterns in living organisms.

FAQs & Answers

  1. What are genes? Genes are segments of DNA that serve as the basic units of heredity, determining traits passed from parents to offspring.
  2. What is the role of mutations in genetics? Mutations are alterations in the DNA sequence that can lead to genetic variations, affecting traits and potentially causing diseases.
  3. How do traits get passed from parents to offspring? Traits are passed through genes inherited from both parents, which come together during fertilization to form a complete set of genetic instructions.
  4. What is inheritance in biology? Inheritance refers to the process by which genetic information is transmitted from one generation to the next, influencing the traits of an organism.
