Traits can be either acquired or inherited. Acquired traits are not heritable and result from external factors like injury or disease, while inherited traits like eye color, height, and disease susceptibility are passed down from parents through DNA. Some traits have both inherited and acquired aspects, such as skin color which is determined by both genes and sun exposure, and earlobe attachment and dimples which have genetic components.

2.  Traits are defined as any
observable feature of an
organism .
 They may ACQUIRED or INHERITED.

3. An acquired characteristic is a
non-heritable change in function of
living biotic material caused after
birth by disease, injury etc.

4. Tanning of skin , it doesn’t causes any
change in the germ cell of DNA and hence
Is not passed onto next generation.

5. O Inherited traits are those which are
inherited from parents. These usually
include physical traits, including eye color,
height, skin tone, hair color, and
susceptibility to certain diseases like
diabetes.
O DNA is the material responsible for
inherited traits in human beings

6. Some traits are both!
 Skin color is a combination trait:-
 Inherited part: Receive genes for skin color from
parents
 Acquired part: Amount of time in the sun determines
level of tan

7. *Earlobe:-
In some people, the ends of the earlobes are attached to the skin on
the neck while others have detached earlobes.
*Dimples
The presence of dimples has a dominant pattern of inheritance, which means
that offspring will have dimples if they receive dominant alleles from both
parents or inherit a dominant allele from either parent.
