gene interaction

Question 1

when the recessive allele of one gene masks the effects of either allele of the second gene

Answer 1

recessive epistasis

Question 2

caused by the dominant allele of one gene, masking the action of either allele of the other gene

Answer 2

dominant epistasis

Question 3

one dominant allele directly suppresses another gene’s function

Answer 3

dominant supression

Question 4

two genes work together to produce a phenotype, both dominant alleles are required

Answer 4

complementary gene

Question 5

occurs when two different genes produce the same phenotype, and having at least one dominant alleles at either locus is sufficient to express the dominant trait

Answer 5

duplicate gene
