Types Of Eptistasis

Front 1

recessive

Back 1

9:3:4

1 pair of homozygous recessive alleles will cause full expression of mutant and other recessive pair will cause partial mutant

Front 2

Dominant

Back 2

12:3:1

The dominant form of one allele will cover up the mutant in any case; mutants only appear when this allele is in homozygous recessive form

Front 3

duplicate recessive

Back 3

9:7

any homozygous recessive allele pair will show the mutant

Front 4

duplicate dominant

Back 4

15:1

any dominant form of either of the two alleles will cover up the mutant, genotype must be homozygous of all genes to be mutant

Front 5

supressor

Back 5

13:3

the presence of one pair of homozygous recessive alleles causes a mutant but the when two fully homozygous recessive are paired together they are wild type
