a•) Incomplete Dominance
b•) Co-Dominance
c•) Multiple Allelism
d•) Both (b) & (c)

Answer 1

d)both b&c-it is an example of both multiple allelism and co dominance.

Answer 2

❣the ri8 answer is Option (d)...

☸blood group is determined by 3alleles... i.e. Ia, Ib and I.... as blood group is determined by more than 2 alleles..so it is a case of MULTIPLE ALLELISM.... this multiple allelism can be studied only in a population.. because an individual call have a Max of 2allele as we are diploid

☸here none out of Ia and Ib are dominant over each other... they both Express themselves when present together... i.e. we get blood group AB when Is and Ib are present together... so it's a case of CODOMINANCE

HOPE IT HELPS YOU...
