Study Notes
Genetics and Evolution
- This unit details DNA structure and function, and explores the concept of evolution.
- The development of biology is a product of collaborative efforts from various scientists, including Watson, Crick, Nirenberg, Khorana, Kornberg, Benzer, and Brenner.
- Early work on heredity and variation was conducted by Mendel and his followers. However, the nature of mechanisms determining traits was unclear.
- Mendel's work laid the groundwork for subsequent investigations in genetics, providing important insights into the fundamental aspects of heredity and variation. This work utilizes statistical analysis and mathematical reasoning.
- Understanding human traits, including similarities and variations between parents and children, and among siblings.
- Early human knowledge of variation stemmed from selective breeding of plants and animals for desirable traits. Humans have selected animals since 8000-10000 years ago.
Chapter 4: Principles of Heredity and Variation
- Genetics is a branch of biology focusing on heredity and variation.
- Heredity is the process of passing traits from parents to offspring.

- Variation refers to dissimilarities in traits among offspring and parents.

Chapter 5: Molecular Basis of Heredity
- This chapter explores the molecular components of heredity.
Chapter 6: Development
- This chapter examines the mechanisms driving development
- Molecular genetics, structural biology, and bioinformatics provide further insight into the molecular basis of development.
Chapter 4.1: Mendel's Laws of Heredity
- Mendel conducted hybridization experiments on pea plants, observing traits like seed shape (round, wrinkled), seed color (yellow, green), flower color (purple, white), pod shape (inflated, constricted), pod color (yellow, green), flower position (axial, terminal), and stem height (tall, dwarf).
- Mendel's experiments involved large sample sizes and successive generations, establishing the validity of his proposed laws. 

- His work highlighted the fundamental framework underlying heredity principles and was later expanded upon by other scientists which enabled the understanding of natural phenomena and their complexities.
- Example traits analyzed include tall or dwarf pea plants, yellow or green seeds.
Chapter 4.2: Inheritance of one gene
- Mendel crossbred tall and short pea plants, observing traits.
- The F1 generation showed only the dominant trait (tall).

- The F2 generation exhibited a 3:1 ratio of dominant (tall) to recessive (short) traits.

- Traits of parents were not blended in offspring but inherited separately.

4.2.1 Law of Dominance
- Traits are governed by discrete units (factors—now known as genes).

- Traits are presented as pairs of factors.

- When a pair of factors are dissimilar the dominant factor's trait is visible. The other factor is considered recessive.
4.2.2 Law of Segregation
- During gamete production, pairs of factors (alleles) separate randomly.
- Each gamete receives one factor from each pair.
4.3: Inheritance of two genes
- Mendel crossbred plants with two contrasting traits (e.g., yellow/green seed color and round/wrinkled shape).

- The F1 generation showed only one set of traits for both features, and the F2 generation demonstrated a complex 9:3:3:1 phenotype ratio.

4.3.1 Law of Independent Assortment
- Genes for different traits are inherited independently of one another.
- The inheritance of one trait does not influence the inheritance of another.
4.4: Multiple Gene Inheritance
- Some traits are controlled by multiple genes.
4.5: Pleiotropy
- A single gene can influence multiple traits.
- Example: Phenylketonuria (PKU)
4.6: Sex Determination
- Sex is often determined by chromosomes (e.g., XX for female, XY for male in humans).
- Different organisms may have different systems for determining sex (e.g., XO in some insects, ZW in birds).
4.7: Mutations (or Variations)
- Changes in DNA sequences.
- Can lead to new variations or disorders.
4.8: Genetic Disorders
- Conditions caused by mutations in genes or chromosomes.
- Examples include cystic fibrosis, sickle-cell anemia, hemophilia, and color blindness.
- Pedigree analysis is useful for studying inheritance patterns of traits in families.
