Epigenetic Inheritance

Question 1

Heritable changes in phenotypic frequency across generations, but with NO changes in genotypic or allele frequencies

Answer 1

Epigenetic Inheritance

Question 2

A term coined by C.H. Waddington in 1942

Answer 2

Epigenetics

Question 3

Who coined the term Epigenetics?

Answer 3

C.H. Waddington in 1942

Question 4

Epigenetics

Answer 4

Alterations in gene expression, but where the DNA itself remains unchanged

Question 5

Made across the genome at each generation to define cell types and patterns of gene expression in the developing embryo

Answer 5

Epigenetic Marks

Question 6

Example of Epigenetic Marks

Answer 6

• Methylation
• Acetylation

Question 7

What is defined by these epigenetic marks?

Answer 7

define which genes are turned on and off

Question 8

Implications

Answer 8

• Epigenetic Effects
• Epigenetic Inheritance

Question 9

Epigenetic Effects

Answer 9

The same genome could express different phenotypes (behavioral traits)

Question 10

Epigenetic Inheritance

Answer 10

Really rapid evolution could take place without changes in the genetic code
