The synthesis of starch in pea seeds is controlled by a single gene. This gene has two alleles,$B$ and $b$. If the shape of the pea seed is considered as the phenotype,what type of inheritance does this represent?

Mendel performed a test cross to determine the:

Mendel studied seven traits of pea plants controlled by genes. On how many different chromosomes are these genes located?
