Overall variations in individuals of same species are brought about by……
a) genetic factor
b) environmental factors
c) both a and b
d) none of these
Some variations have few distinct forms and are called……..
a) continuous variation
b) discontinuous variations
c) inheritable variations
d) non-inheritable variations
Explanation:Variation in phenotypic traits in which types are grouped into discrete categories with few or no intermediate phenotypes e.g. ABO blood group.
Some variations do not have few distinct forms and have wide range from one extreme to other are called……..
a) continuous variation
b) discontinuous variations
c) inheritable variations
d) non-inheritable variations
Explanation:Continuous variation is the type of genetic variation in which a particular character shows an unbroken range of phenotypes. Generally, it is the most common type of genetic variation governed by the presence of many genes. The weight and height of animals are examples of continuous variation.
