Vaselesa [24]2 years ago
4 0

krek1111 [17]

Answer:

The correct answer is ''The scientific study of heredity''

Explanation:

Genetics is a branch of biology that studies how hereditary characters are transmitted from generation to generation and the diversity that exists among living beings. Inheritance is the physical and biological characteristics that we share with our family and that can determine our appearance and our biological characteristics, that is, our phenotype (eye color, skin type, etc.) as well as our internal characteristics. All of this is largely derived from our genetic components, that is, our genotype.
