Course Description

COURSE DESCRIPTION

The course will cover the basic principles of classical genetics and inheritance as espoused by Mendel; the foundations that will enable students understand and apply genetic principles and concepts at higher levels.

It also provides an introduction to the fundamental principles of evolution, and aims to show how evolutionary changes explain the variations observed and how we can manage this change for the benefit of the world around us and the human race in general. 

COURSE JUSTIFICATION

The course unit introduces Genetic and evolutionary concepts and demonstrates how these underpin other disciplines. It also develops the student’s capacity for scientific evaluation and analysis, and critical appraisal, skills which will also be applied in other disciplines in the biological sciences, and later in the work place. The knowledge gained will be applied in teaching but can also be applied in research in areas of medicine and public health, agriculture and natural resources conservation if the learner chooses to pursue further studies.

EXPECTED LEARNING OUTCOMES

By the end of the course unit, students should be able to:

·                     Describe the processes of mitosis and meiosis in plants and animals as the          basis of continuity of life

·                     Describe the structure and composition of a chromosome and Nucleic acids         (DNA and RNA).

·                     Describe Evidence of DNA as a hereditary material and protein synthesis

·                     Explain the importance and contribution of meiosis to variations

·                     Compare Pre-Mendelian, Mendelian and modern theories of inheritance

·                     apply Mendel’s first and second laws of inheritance to solve related genetic         problems

·                     Explain Crossing-over and Recombinant genes

·                     Map genes on chromosomes basing on cross-over values (COV) or cross-over      frequencies (COF) between them

·                     Discuss different factors that are responsible for sex determination in plants        and animals and differentiate patterns of inheritance related to sex

·                     Explain the causes of sex abnormalities in man and enumerate symptoms associated with each abnormality
