16
Q

Natural selection was proposed by two naturalists :

A

Charles Darwin and Alfred Russel Wallace

17
Q

A heritable trait that aids the survival and reproduction of an organism in its present environment

18
Q

Occurs when there is a disruption in the complementary base pairing of the DNA or alteration within the nucleotide sequences

A

Genetic mutation

19
Q

This is a change in the DNA sequence of the gene

A

Genetic mutation

20
Q

The collection of genes in a population

21
Q

The genetic makeup of an individual

22
Q

The traits of an individual

23
Q

It is defined as a variant form of a gene

24
Q

Basic unit of heredity

25
The random manner in which a trait can be favored or lost in a given population
Genetic drift
26
Is a change in the gene pool of a population due to chance
Genetic drift
27
Simple effect of change
Genetic drift
28
The change in frequency of an existing gene variant in the population due to random chance.
Genetic drift
29
Genetic drift can also be magnified by....
Natural and human-caused events
30
A few individuals from a population start a new population with a different allele frequency than the original population.
Founder effect
31
Occurs when a population undergoes an event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing
Population bottle neck
32
The transport of genes by migrating individuals
Gene flow
33
Occurs during meiosis when chromosomes exchange genes
Recombination
