It is impossible for these individuals to have a chlld with type O blood.

Is when heterozygotes show a phenotype intermediate between those of the two homozygotes.

Involves the expression of both alleles at a locus producing two different phenotypes.

Is only found in mammalian enzyme production.

Involves one allele having more than one phenotypic effect.
