Options:
Answer:
B
Solution:
Dominance -( IAIO, IBIO)- the phenomenon whereby, in an individual containing two allelic forms of a gene, one is expressed to the exclusion of the other.
Codominance -( IAI B)- a form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed. This results in offspring with a phenotype that is neither dominant nor recessive.
Multiple alleles- IA, IB& IO- 3-different allelic forms of a gene.
