Weba hybrid means that the offspring is heterozygous. in regular mendelian genetics, its genotype would be a dominant allele and a recessive allele (ex. Aa). in incomplete dominance and codominance (non-mendelian genetics), it would mean that it has two different alleles (ex. AB or A^1 B^1). ( 2 votes) Upvote.
