When both alleles of a pair are fully expressed in a heterozygous condition,it is called $:-$

In shorthorn cattle,genes for red $(R_1)$ and white $(R_2)$ coat colour occur. Crosses between red $(R_1R_1)$ and white $(R_2R_2)$ produced $(R_1R_2)$ roan. This is an example of

In heterozygous condition,the individual expression of both the alleles in the phenotype is exemplified by

What is the phenomenon called where factors produce independent effects in their heterozygous condition?

When two genes with independent expression are present together, they both express their characteristics, and when they are separate, they express their individual characteristics. This phenomenon is observed in which of the following?

If two individuals with $AB$ blood group marry and have a large number of children,the children show $A$,$AB$,and $B$ blood groups in a ratio of $1:2:1$. Since proteins of both $A$ and $B$ types are present in individuals with $AB$ blood group,this is an example of:
