Test bank-Essentials of Genetics, William Klug
8th Edition, Chapter 1
Epigenesis - ANSWER: States that an organism develops from the fertilised egg by a
succession of developmental events that eventually transform the egg into an adult
Preformation - ANSWER: States that the fertilized egg contains a complete miniature
adult, called a homunculus
Cell theory - ANSWER: States that all organisms are composed of basic units called
cells
Spontaneous generation - ANSWER: The creation of living organisms from nonliving
components, disproved by Louis Pasteur
Natural selection - ANSWER: Survival of the fittest
Genetics - ANSWER: The branch of biology concerned with the study of heredity and
variation
Diploid number - ANSWER: A characteristic number of chromosomes of members of
each species
Homologous chromosomes - ANSWER: The chromosomes in diploid cells that exist
in pairs
Mitosis - ANSWER: Chromosomes are copied and distributed so that each daughter
cell receives a set of chromosomes identical to those in the parental cell
Meiosis - ANSWER: The process by which cells receive only one chromosome from
each chromosome pair, resulting number is haploid number
Chromosome theory of inheritance - ANSWER: States that inherited traits are
controlled by genes residing on chromosomes faithfully transmitted through gametes,
maintaining genetic continuity from generation to generation #$%^&

Mutations - ANSWER: Any heritable change in the DNA sequence and are the source %$#$%
of all genetic variation ^&*(*
