In pea plants,if the $Bb$ gene is present in a heterozygous condition for starch grain synthesis,what type of inheritance does the round seed shape exhibit?

How many pairs of contrasting traits were selected by Mendel for his study on garden peas?

Identify the contribution of the following scientists: Hugo de Vries,Carl Correns,and Erich von Tschermak.

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.

$A$ test cross is performed to:

Fruit flies $(Drosophila \text{ } melanogaster)$ are one of the best materials for genetic studies because of all, except:
