Genetic factors are the biological attributes passed down from parents to offspring. These factors are determined by the genes, which are segments of DNA that encode specific traits. Genetic factors play a significant role in determining an individual's physical characteristics, as well as susceptibility to certain diseases and disorders.
Genetic factors are inherited from both parents and are passed down through the egg and sperm cells. Each parent contributes one set of 23 chromosomes to their offspring, resulting in a unique combination of genetic factors in the offspring. These factors can influence traits such as eye color, height, and susceptibility to certain diseases.
Understanding Genes:Genes are the basic units of heredity, and they contain the instructions for building and maintaining the body. Students should learn about the structure of genes and how they determine specific traits.
Inheritance Patterns: Explore the different patterns of inheritance, including dominant and recessive traits, and how genetic factors are passed down from parents to offspring.
Genetic Disorders: Discuss common genetic disorders and how they are caused by mutations or variations in genetic factors. Students should understand how genetic testing and counseling can help in identifying and managing these disorders.
Impact of Environment: Explain how genetic factors interact with environmental influences to shape an individual's traits and characteristics. Discuss the concept of nature versus nurture in determining traits.
Identify the distribution of freshwater and salt water on Earth (e.g., oceans, lakes, rivers, glaciers, ground water, polar ice caps) and construct a graphical representation depicting the amounts and percentages found in different reservoirs.
