A man with blood group $B$ marries a women with blood group $A$ and their first child is having blood group $B$. What is the genotype of child
${I^a}{I^b}$
${I^a}{I^o}$
${I^b}{I^o}$
${I^b}{I^b}$
Blood group of the father is $A$ and blood group of mother is $B$. Then predict the blood group of the progeny -
A gene showing codominance has
Blood group of mother and child are $B$ and $AB $ respectively. The possible blood group of father would be .........
Explain the following terms with example
$(a)$ Co-dominance
$(b)$ Incomplete dominance
In a marriage between male with blood group $A$ and female with blood group $B$, the progeny had either blood group $AB$ or $B$. What could be the possible genotype of parents ?
