1.

Evolution may be defined as

the growth of an individual
a change in an individual during its life
the origin of life
a change in allele frequencies in a population over many generations
2.

A species is a group of organisms that

live in the same habitat
can interbreed to produce fertile offspring and are reproductively isolated from other groups
look identical
have the same number of cells
3.

Allopatric speciation requires

geographical separation of populations
populations in the same area
polyploidy
no selection
4.

Sympatric speciation occurs

without geographical separation
only on islands
only in bacteria
after a mountain range forms
5.

Molecular evidence for evolutionary relationships comes from comparing

body size
habitat
DNA base sequences and amino acid sequences of proteins
behaviour only
6.

Reproductive isolation between two populations means that

they can no longer interbreed to produce fertile offspring
they live far apart
they eat different food
they look different
7.

A prezygotic isolating mechanism is

hybrid sterility
a difference in courtship behaviour
hybrid inviability
failure of the embryo to develop
8.

Mitochondrial DNA is useful for studying evolution because it

does not mutate
is found only in males
is inherited through the female line and mutates at a fairly constant rate
is the same in all species
9.

The first step in allopatric speciation is

reproductive isolation
a change in chromosome number
a barrier preventing gene flow between two populations
hybridisation
