Chromosomes: the basis of heredity: JAMB Biology Past Questions and Answers
What the JAMB syllabus covers in Chromosomes: the basis of heredity
Our summary: DNA and chromosome structure, and how genes separate at meiosis and recombine at fertilization.
- Structure
- Process of transmission of hereditary characters from parents to offsprings
Objectives
- illustrate simple structure of DNA
- illustrate segregation of genes at meiosis and recombination of genes at fertilization to account for the process of transmission of characters from parents to offsprings.
- deduce that segregation of genes occurs during gamete formation and that recombination of genes at fertilization is random in nature.
