xi. outline the benefits of conserving natural resources, prevention of desertification.
xii. identify the bodies responsible for the conservation of resources at the national and international levels e.g. Nigerian Conservation Foundation (NCF), Federal Ministry of Environment, Nigeria National Parks, World Wildlife Foundation (WWF), International Union for Conservation of Nature (IUCN), United Nations Environmental Programme (UNEP) and their activities.
xiii. identify and state the location and importance of game reserves and National parks in Nigeria
D: Heredity and Variations
Fourthly, this section explains why you look a bit like your parents, but are also unique.
(I) Variation In Population
a. Morphological variations in the physical appearance of individuals.
(i) size (height and weight)
(ii) Colour (skin, eye, hair, coat of animals, scales and feathers).
(iii) Fingerprints
b. Physiological variation
(i) Ability to roll tongue
(ii) Ability to taste phenylthiocarbamide (PTC)
(iii) Blood groups
c. Application of discontinuous variation in crime detection, blood transfusion and determination of paternity.
Objectives: Candidates should be able to:
i. differentiate between continuous and discontinuous variations with examples.
ii. relate the role of environmental conditions, habitat and the genetic constitution to variation.
iii. measure heights and weights of pupils of the same age group
iv. plot graphs of frequency distribution of the heights and weights.
v. observe and record various colour patterns in some plants and animals.
vi. apply classification of fingerprints in identity detection.
vii. identify some specific examples of physiological variation among human population.
viii. categorize people according to their physiological variation.
ix. apply the knowledge of blood groups in blood transfusion and determination of paternity.
x. use discontinuous variation in crime detection.
2. Heredity
a) Inheritance of characters in organisms
(i) Heritable characters
(ii) Non-heritable characters
b) Chromosomes – the basis of heredity
(i) Structure
(ii) Process of transmission of hereditary characters from parents to offsprings.
c) Probability in genetics and sex determination.
d) Application of the principles of heredity in:
i) Agriculture
(ii) Medicine
e) Sex – linked characters e.g. baldness, haemophilia, colour blindness, etc.
Objectives: Candidates should be able to:
i. determine heritable and non-heritable characters with examples.
ii. illustrate simple structure of DNA
iii. 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.
iv. deduce that segregation of genes occurs during gamete formation and that recombination of genes at fertilization is random in nature.
v. analyze data on cross-breeding experiments.
vi. apply the principles of heredity in the production of new varieties of crops and livestock through cross-breeding.
vii. deduce advantages and disadvantages of out-breeding and in-breeding.
viii. analyze elementarily the contentious issues of genetically modified organisms (GMO) and gene therapy and biosafety.
ix. apply the knowledge of heredity in marriage counselling with particular reference to blood grouping, sickle-cell anaemia and the Rhesus factors.
x. describe the significance of using recombinant DNA materials in the production of important medical products such as insulin, interferon and enzymes.
xi. identify characters that are sex linked.
E: Evolution
Finally, evolution explains how life on Earth has changed over millions of years.
1. Theories of evolution
a) Lamarck’s theory
b) Darwin’s theory
c) organic theory
Objectives: Candidates should be able to:
i. relate organic evolution as the sum total of all adaptive changes that have taken place over a long period of time resulting in the diversity of forms, structures and functions among organisms.
ii. explain the contributions of Lamarck and Darwin to the theory of evolution.
iii. state the evidences in support of organic evolution
2. Evidence of evolution
Objectives: Candidates should be able to:
i. mention the evidences for evolution such as fossil records, comparative anatomy, physiology and embryology.
ii. trace evolutionary trends in plants and animals.
iii. state the evidence of modern evolutionary theories such as genetic studies and the role of mutation.
