The statement that indicates fertilization is the passing of genetic instructions from one generation to the next is false.
Explanation:
The passing of genetic instructions from one generation to the next is called inheritance or heredity. Through inheritance, parents can transfer to their offspring structural and functional information that identifies them as members of a species.
Fertilization, on the other hand, is the process in which two gametes —male and female— join together to produce a new living organism, with similar morphological and functional characteristics.
Both fertilization and inheritance are related, because they involve the transmission of genetic information from parents to children. However, to <u>say that fertilization is the passage of genetic instructions from one generation to the next is false</u>.

With the passage of time, as scientists learn and discover, the scientific classification changes based on these new studies.
