The phenotype of an individual may be affected if the modified allele produces
$(a)$ No enzyme at all
$(b)$ The normal/less efficient enzyme
$(c)$ $A$ non-functional enzyme
Only $(a)$ is correct
$(a)$ and $(c)$ are correct
$(b)$ and $(c)$ are correct
Only $(c)$ is correct
In $F_2$ generation of monohybrid cross the cause of $1 : 2 : 1$ phenotypic ratio is
${F_1}$ hybrid is intermediate between the two parents. The phenomenon is
In a Mendelian monohybrid cross, the $F_2$ generation shows identical genotypic and phenotypic ratios. What does it tell us about the nature of alleles involved? Justify your answer.
In which cross will you get most pink flowers?
$F_2$ generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as $1 : 2 : 1$. It represents a case of
