Genetic Engineering/Selective Breeding

Front

What is genetic engineering?

Back

Genetic engineering is the process of using technology to alter the genetic makeup of an organism by inserting, deleting, or modifying genes.

Front

What is selective breeding?

Back

Selective breeding is the process of choosing specific organisms with desirable traits to reproduce, aiming to produce offspring with those traits.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, represented by the alleles (e.g., BB, Bb, bb) that an organism carries.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype and environment (e.g., brown fur, blue eyes).

Front

What does the term 'dominant trait' mean?

Back

A dominant trait is a genetic trait that is expressed in the phenotype even when only one copy of the allele is present (e.g., B in Bb or BB).

Front

What does the term 'recessive trait' mean?

Back

A recessive trait is a genetic trait that is only expressed in the phenotype when two copies of the allele are present (e.g., bb).

Front

What is the role of DNA in genetic engineering?

Back

DNA carries the genetic information of an organism and is the target for modification in genetic engineering.

Front

What is bioluminescence?

Back

Bioluminescence is the ability of certain organisms to produce and emit light, often through a chemical reaction involving luciferin.

Front

What is the significance of the 'B' allele in hair color?

Back

The 'B' allele represents the dominant trait for brown hair, while 'b' represents the recessive trait for lighter hair.

Front

What is the process of cutting DNA called?

Back

The process of cutting DNA is often referred to as 'DNA cleavage' and is a key step in genetic engineering.
