What this unit covers

• Chromosomes, genes and proteins: Identify that chromosomes consist of DNA, which holds genetic information in the form of genes.
• Chromosomes, genes and proteins: Clarify that a gene is a segment of DNA that encodes a protein.
• Mitosis: Explain mitosis as a process of nuclear division that results in cells that are genetically identical, without needing to detail the specific stages involved.
• Mitosis: Identify the functions of mitosis in promoting growth, repairing damaged tissues, replacing cells, and facilitating asexual reproduction.
• Meiosis: Identify that meiosis plays a role in creating gametes.
• Meiosis: Explain meiosis as a type of division that reduces the chromosome count from diploid to haploid, leading to cells that are genetically distinct (specific stages of meiosis do not need to be detailed).
• Monohybrid inheritance: Explain inheritance as the passing of genetic information from one generation to the next.
• Monohybrid inheritance: Define genotype as the genetic composition of an organism, specifically regarding the alleles it possesses.
