adaptability to changing conditions
7
The perch can lay 40,000 eggs. What key idea of natural selection is this?
phenotype differences in individuals can be inherited
individuals produce an excess of offspring
individuals vary in their phenotypes
humans select for predetermined traits
8
A phenotype
a result of genetic recombination
the genes of a particular individual
the set of traits expressed in an individual
An adaptation that creates a new species
9
Which statement is not correct?
Speciation can be caused by either natural or random process
speciation can't occur without geographic isolation
polyploidy is an example of sympatric speciation
geographic isolation can lead to reproductive isolation
10

the absence of a favorable environment nearby
the rapid rate of environment change
13
Which of the following processes create genetic diversity in a population?
A and C
recombination
allele division
