1.5 SCOPE OF STUDY
This
study, as the title implies, has used man as a case study, hence all
attempt to make the subject of reproduction clearer has been duly
focused on man. Some of the areas covered include pregnancy and child
birth.
1.7 DEFINITION ODF TERMS
The following definition of terms has been provided to ensure uniformity throughout the study.
Reproduction: The sexual or asexual process by which organisms generate new individuals of the same kind; procreation.
Individual:
An individual belonging to a group of organisms (or the entire group
itself) having common characteristics and (usually) are capable of
mating with one another to produce fertile offspring.
Fertility: The state of being fertile or fruitful; fruitfulness; productiveness.
Sperm: The male reproductive cell; the male gamete; “a sperm is mostly a nucleus surrounded by little other cellular materialâ€.
Fertilization: the union of male and female gametes during sexual reproduction, to form a zygote.
Population:
A group of individuals of the same species occupying a particular
geographical area. Population may be relatively small and closed, as on
an island or in a valley, or they may be more diffuse and without a
clear boundary between them and a neighbouring population of the same
species
Gene: A gene is a molecular unit of heredity of a living organism.
Traits: A distinguishing feature, as of a person’s character.
Phenotype:
The physical appearance or biochemical characteristic of an organism as
a result of the interaction of its genotype and the environment.
Heredity:
The passing on of traits to offspring from its parents or ancestor.
This is the process by which an offspring cell or an organism acquires
or becomes predisposed to the characteristics of its parent cell or
organism.
Genotype: The genetic constitution of an individual organism.
Offspring: the immediate descendants of an organism.
Mating: The meeting of individuals for sexual reproduction.
Breeding: The mating and reproduction of offsprings by animals.
Gametes: Gametes are reproductive cells that unite during sexual reproduction to form a new cell called a zygote.
Survival: A natural process resulting in the evolution of organisms best adapted to the environment.
Zygote:
The cell formed by the union of two gametes, especially a fertilized
ovum before cleavage. A zygote is the cell that results from
fertilization.
Gestation: In mammals, the time between conception and birth, during which the embryo or fetus is developing in the uterus.
Menopause: Cesation of menstruation in the human female, occurring usually around the age of 50.
Evolution: A gradual process in which something changes into a different and usually more complex or better form.

ABSRACT - [ Total Page(s): 1 ]This study examined reproduction in mammals using man as a case study. In the study, some of the main features of reproduction in man are explored. After considering some of the various aspects of reproduction in man and the challenges faced, we move to consider in particular, pregnancy and childbirth. To this effect, a questionnaire was designed that addressed issues relating to pregnancy and childbirth. The primary audiences for the questionnaire were pregnant women/nursing mothers and medical ... Continue reading---
