What is a transgene?
A
A mutant chromosome
B
A gene that is different as a result of genetic engineering
C
The offspring of a genetically engineered animal
D
A gene that does not carry any traits
Explanation: 

Detailed explanation-1: -With genetic engineering it is possible to introduce any gene into a genome. The introduced gene is either a cisgene, if the manipulated gene is derived from the same species or a sexually compatible species, or a transgene, if the gene is derived from a species that is not compatible with the host.

Detailed explanation-2: -A transgene is an experimentally constructed piece of DNA that has integrated into the genome of a recipient organism. Once integrated into germ cells, subsequent generations inherit the transgene, referred to as stable transgene transmission.

Detailed explanation-3: -A transgene is a gene or a segment of DNA that is introduced into the genome of an organism. It comes from an organism especially of another species. This gene is introduced to another organism that makes the latter acquire new property or capability.

Detailed explanation-4: -Foreign DNA (the transgene) is defined here as DNA from another species, or else recombinant DNA from the same species that has been manipulated in the laboratory then reintroduced. The terms transgenic organism and genetically modified organism (GMO) are generally synonymous.

Detailed explanation-5: -A transgene is a gene that has been transferred naturally, or by any of a number of genetic engineering techniques, from one organism to another. The introduction of a transgene, in a process known as transgenesis, has the potential to change the phenotype of an organism.
