Question

The production of transgenic animals involves which type of genetic material introduction?

Options

• Random natural mutations occurring spontaneously

• Artificial introduction of genes into host embryos through biotechnological techniques

• Selective breeding of animals with desired natural traits

• Chemical treatment to induce genetic variation

Answer 1

The production of transgenic animals fundamentally relies on artificial introduction of genes into host embryos through purposeful biotechnological techniques. This distinguishes transgenic animals from naturally occurring variants or selectively bred animals. The process requires deliberate isolation of a desired gene and its intentional insertion into an embryo or host cell using vectors or direct injection methods, followed by development and verification of expression.
