Population Genetics: Crash Course

What is population genetics?

• How genes change over time

• How the genes of a specific population change over time.

• How a population changes over time.

• How the genes of a population changing over time leads to evolution.

What is a population?​ ​ ​ (a)  

• A group of individuals that can interbreed.
• a group that can mate
• a group of individuals that live near each other.&

What is it called when you measure how frequently alleles pop up in a population?

What are the five influences that can change allele frequency in a population's genetics?

Who were the scientists that explained how Mendelian genetics works for a whole population?​ (a)   ​ (b)  

• Hardy
• Weinberg
• Darwin
• Mendel

Are you enjoying the video lesson?

• Yes

• No

To make the Hardy-Weinberg Principle work, what must NOT happen in a population?

• evolution

• random mating

• no mutations

• large populations

Organize these options into the right categories

Groups:

(a) Dominant alleles

,

(b) Recessive Alleles

• q

• p

• w

• W

According to Hardy Weinberg, what MUST p + q equal?​ (a)  

• 1
• 100
• 2
• 25

Looking at PHENOTYPES, what can you not determine in terms of allele frequencies?

• How many homozygous recessive individuals there are.

• How many dominant alleles there are.

• How many recessive alleles are hidden in a heterozygous pair.
