Question

Word genetics come from
A. Gene
B. Genesis
C. Genome
D. Genomics

Answer 1

Genetics is a branch of science that deals with the study of hereditary.
Genetics is the study of inheritance as well as the variation of characters from parents to offspring.
Inheritance is the process by which characters are passed on from parents to progeny.

Complete answer:
Heredity is a biological process whereby a parent passes certain genes onto their children or offspring.
Every child inherits genes from both of their biological parents and these genes, in turn, express specific traits.
So, the study of this hereditary is known as genetics.
The word genetics arises from the Greek word genesis.
Genesis means origin or a beginning of a process.
The word genetics was coined by William Bateson.
Inheritance as we know is the process by which characters are passed on from parents to their offspring and this causes the basis of hereditary.
Variation is the term or the degree by which progeny differ from their parents.
Humans knew from early 8000 to 1000 B.C that one of the causes of variation was hidden in the sexual reproduction.
Gene is something which was stably passed down unchanged from parents to offspring through the gametes, over successive generations and these things are known as genes.
Gene is known as the unit of inheritance.
Genome is a complete set of genes or genetic material.
Genomic is the study of whole genomes of organisms, and incorporates elements from genetics.

So, the correct option is option B. Genesis.
