19.1 - The Hardy-Weinberg Principle

Question 1

Species

Answer 1

A group of similar organisms that can interbreed to produce live offspring that can also reproduce.

Question 2

Population

Answer 2

A group of organisms of the same species that live in a defined area and time.

Question 3

Community

Answer 3

Made up of all the different populations that interact within an ecosystem.

Question 4

Genes

Answer 4

Are carried on chromosomes and control the inheritance of traits.
ex.) fur color in animals.

Question 5

Allele

Answer 5

A gene can have more than one form. Each form of a gene is called an allele.
ex.) fur colour: black allele, white allele.

Question 6

Gene pool

Answer 6

All the genes that collectively occur within a population at a certain time.

Question 7

Genotype frequency

Answer 7

The proportion of a population within a certain genotype.

Question 8

Phenotype frequency

Answer 8

The proportion of a population with a particular phenotype

Question 9

Allele frequency

Answer 9

The rate of occurrence of a particular allele in a population with respect to a particular gene.

Question 10

Hardy-Weinberg conditions

Answer 10

1. Population is large
2. Mates are chosen on a random basis
3. There are no mutations.
4. There is no migration.
5. No natural selection

Question 11

Microevolution

Answer 11

The change in allele and genotype frequencies.

Question 12

What does it mean if conditions for HW equilibrium aren’t met?

Answer 12

The population is evolving
