1. Basic Biology

The chapter discusses the structure of chromosomes, the cell cycle, and the mechanics of cell division through mitosis and meiosis. Additionally, it introduces genetics, focusing on Mendel’s three laws of inheritance and key genetic terms. Concepts of chromosomal structures, cellular processes related to reproduction, and the principles of heredity are explained in detail.

  • 1.1.2

    The Cell Cycle

    The cell cycle comprises the processes of interphase and mitotic phase, essential for cell growth and division.

    Learning Practice

  • 1.1.3

    Mitosis

    Mitosis is the process of cell division resulting in two identical daughter cells, occurring in somatic cells.

  • 1.1.4

    Meiosis

    Meiosis is a specialized form of cell division that reduces the chromosome number by half, producing four haploid gametes.

    Genetics – Mendel’s Laws Of Inheritance

    This section introduces the fundamental concepts of genetics and the laws of inheritance established by Gregor Mendel.

    Learning

  • 1.2.1

    Mendel's Laws

    Mendel's Laws describe the principles of inheritance that dictate how traits are passed from parents to offspring.

    Key Genetic Terms

    This section defines essential genetic terms that are crucial for understanding heredity and variation.

  • 1.2.3

    Mendel's Laws

    This section outlines Gregor Mendel's foundational laws of inheritance, explaining dominance, segregation, and independent assortment through interactive examples.

    Learning

  • 1.2.3.1

    Law Of Dominance

    The Law of Dominance states that in heterozygous conditions, the dominant allele masks the effect of the recessive allele.

    Learning Practice

  • 1.2.3.2

    Law Of Segregation

    The Law of Segregation states that allele pairs separate during gamete formation, ensuring that each gamete receives only one allele.

    Learning Practice

  • 1.2.3.3

    Law Of Independent Assortment

    The Law of Independent Assortment states that genes for different traits are inherited independently when they are on different chromosomes.
