Two heterozygous parents are crossed. If the two loci are linked what would be the distribution of phenotypic features in `F_(1)` generation for a dihybrid cross?

Explanation

In case of two heterozygous parents,showing linkage result will be:
Parents:BbLi X BbLi genotype
(Blue long) (Blue long) Phenotype
In `F_(1)` all the combinations may show parental characters as the genes are completely linked.With all possible genotypes in`F_(1)` ,progeny may exhibit blue long type of phenotype in above case.However in case of incomplete linkage ,parantal combination will be more and new combination will be less in number.
