In the human \(\mathrm{ABO}\) blood system, the alleles \(\mathrm{A}\) and \(\mathrm{B}\) are dominant to \(\mathrm{O}\). What will be number of different possible genotype?
1 4
2 6
3 8
4 12
Explanation:
Formula to calculate number of genotype for multiple allelism \(\dfrac{n(n+1)}{2}\) if where \(\mathrm{n}=\) no. of alleles controlling the trait. Thus, the number of different possible genotype would be 6 viz., \(\mathrm{AA}, \mathrm{AB}, \mathrm{AO}, \mathrm{BB}, \mathrm{BO}\) and \(\mathrm{OO}\).

Which idea is depicted by a cross in which the \({F_1}\) generation resembles both the parents?
1 Incomplete dominance
2 Inheritance of one gene
3 Codominance
4 Complete dominance
Explanation:
Codominance is a genetic sequence where neither allele is dominant or recessive and both get expressed equally in the heterozygote. In this both the alleles are capable of expressing themselves independently when present together results in a phenotype which is median between both the parental homozygous phenotypes, with that resembling both of them. Example of codominance is red coat colour in cattle.
