Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Crossing two individuals that have similar desirable characteristics is called ____
A
cloning
B
genetic engineers
C
gene therapy
D
inbreeding
Explanation: 

Detailed explanation-1: -inbreeding, the mating of individuals or organisms that are closely related through common ancestry, as opposed to outbreeding, which is the mating of unrelated organisms.

Detailed explanation-2: -Crossing two individuals that have similar desirable characteristics is called GENETIC ENGINEERING. In SELECTIVE BREEDING, organisms with desired traits are chosen to be parents of the next generation. The process by which genes from one organism are transferred into the DNA of another organism is called INBREEDING.

Detailed explanation-3: -Hybridization is the mating of genetically differentiated individuals or groups and may involve crossing individuals within a species (also known as line crossing or strain crossing) or crossing individuals between separate species.

Detailed explanation-4: -Hybridization is when breeders cross two genetically different individuals in hopes that the offspring will have the best traits from both parents.

Detailed explanation-5: -Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce.
