$A$ common test to find the genotype of a hybrid is by

Mendel published his work on the inheritance of characters in $1865$,but it remained unrecognized until $1900$ because:
$(a)$ He could not provide any physical proof for the existence of factors.
$(b)$ His concept of factors as stable,discrete units that controlled the expression of traits did not find acceptance from his contemporaries.
$(c)$ Mendel's approach of using mathematics to explain biological phenomena was considered ahead of its time and unconventional.
$(d)$ Communication was not easy (as it is now),and his work could not be widely publicized.

Determine the number of possible gametes produced by an organism with the genotype $AaBbCc$.

$A$ modified allele is equivalent to an unmodified allele when it produces what?

In the case of $PTC$ tasters and non-tasters in humans,$T$ represents the dominant allele and $t$ represents the recessive allele. Which of the following genotypes is unable to taste $PTC$?

$A$ cross in which an organism showing a dominant phenotype is crossed with the recessive parent in order to know its genotype is called
