Which of the following conditions represents a case of co-dominant genes?
A gene expresses itself, suppressing the phenotypic effect of its alleles.
Alleles, each of which produces an independent effect in a heterozygous condition.
Genes that are similar in phenotypic effect when present separately, but when together, interact to produce a different trait.
Alleles, both of which interact to produce a trait, which may or may not resemble either of the parental types.

Co-dominance is the phenomenon when the two genes neither show dominant-recessive relationship nor show intermediate condition- but both of them express themselves simultaneously- This has been reported in roan character of cattle -i-e- patches of 2 different colours on the skin-
