<h3>Explanation:</h3>
- Gene therapy is the manipulation of genes in the genetic make up of an individual to eradicate the inheritable genetic disorders.
- The second use is the genetic engineering. Which is the genetic changes of an organism or micro organism to produce a desirable product.

Explanation:
Answer:
d. The two species have a different number of chromosomes, resulting in a postzygotic barrier.
Explanation:
The two species i.e. sheep and goat have different number of chromosomes that resulting in a postzygotic barrier. Sheep has 56 number of chromosomes whereas goat has 60 number of chromosomes that causes postzygotic barrier in the offspring produced from the fusion of these two species. Postzygotic barrier leads to the creation of a hybrid that is sterile and unable to produce offspring because of difference in chromosome number.
