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.

What we have learnt
- Chromosomes are made of DNA and proteins and are vital for genetic inheritance.
- The cell cycle consists of interphase and the mitotic phase, leading to cell division.
- Mendel's laws explain how traits are inherited and include concepts such as dominance, segregation, and independent assortment.
Key Concepts
- -- Chromosome
- Thread-like structures made of DNA and proteins found in the nucleus, containing genes.
- -- Mitosis
- A type of cell division that results in two identical daughter cells.
- -- Meiosis
- A special type of cell division that produces gametes with half the chromosome number, leading to genetic variation.
- -- Law of Dominance
- In heterozygous individuals, the dominant allele manifests in the phenotype.
- -- Law of Segregation
- Allele pairs separate during gamete formation, allowing each gamete to carry one allele.
- -- Law of Independent Assortment
- Different genes segregate independently of one another in the formation of gametes.
