Answer 1

The correct option is C Both statements are true and Statement II is correct explanation of Statement I.

$\bullet$ Physical personality traits are passed down from one generation to the other and this is known as heredity.
$\bullet$ The traits are encoded in the DNA of the individual in the form of specific sequences known as genes.
$\bullet$ During fertilisation, these genes are passed from the parents to the offspring via chromosomes. These are carried by the sex cells which are involved in fertilisation, also known as gametes.
Thus, chromosomes can be said to determine the traits of an individual.
