Epistasis

Question 1

What is epistasis?

Answer 1

One gene influences the expression of another gene

Question 2

What is the phenotype ratio in most cases for epistasis?

Answer 2

9:3:4

Question 3

What is the key term that describes the gene that is in control of the other gene?

Answer 3

Epistatic

Question 4

What does the term epistatic refer to?

Answer 4

An epistatic gene refers to a gene that affects expression of other gene

Question 5

What is the key term that describes the gene that is affected by the epistatic gene?

Answer 5

Hypostatic

Question 6

What does the term hypostatic refer to?

Answer 6

A hypostatic gene refers to a gene that is affected by the epistatic gene

Question 7

What does the term epistatic recessive refer to?

Answer 7

Epistatic recessive means the hypostatic gene will not be expressed if the epistatic gene is homozygous recessive

Question 8

What does the term epistatic dominant refer to?

Answer 8

Epistatic dominant means the hypostatic gene will not be expressed if the epistasis gene is homozygous dominant or recessive

Question 9

How would you determine whether the type of gene interaction was epistatic dominant or recessive?

Answer 9

If the dominant allele is the allele says no then it is epistatic dominant.
If the recessive allele is the allele says no then it is epistatic recessive
