Pea shape in Mendelian experiments exists in two sharply distinct phenotypes; round and wrinkle; so they have……….phenotypes.
a) qualitative
b) quantitative
c) both a and b
d) none of them
Explanation: they show discontinuous variations because round and wrinkle shape seeds have distinct phenotypes
Which of the following traits show qualitative phenotypes?
a) 4 O’ clock flower color
b) ABO blood group system
c) seed shape in garden pea
d) all of these
Which of the following traits show quantitative phenotypes and exhibit continuous variations?
a) weight and height
b) intelligence and skin color
c) grain color in wheat
d) all of these
Mendel focused on
traits that showed ……..different phenotypes.
a) qualitative
b) quantitative
c) both a and b
d) none of them
Explanation: which could be determined by two alleles of a single gene
Mendel focused on
traits that showed ……..different phenotypes.

d) none of them
Explanation: which could be determined by two alleles of a single gene
The wide range of phenotypes of a quantitative trait can’t encoded by………
