Which of the following characteristics represent 'Inheritance of blood groups' in humans? a. Dominance b. Co-dominance c. Multiple allele d. Incomplete dominance e. Polygenic inheritance
Explanation
ABO inheritance shows dominance, co-dominance and multiple alleles.
Detailed Solution
$I^AI^O$, $I^BI^O$ – dominant–recessive relationship
$I^AI^B$ – co-dominance
$I^A$, $I^B$ and $I^O$ – three different allelic forms of a gene (multiple allelism)
So dominance, co-dominance and multiple alleles (a, b and c) are shown.
