Answer: Cloned organism, egg donor, and surrogate mother all contribute to the recombinant technology, and for cases of infertility.
Step-by-step explanation:
The organism to be cloned is utilized by using its genetic composition extracted from its cells. The egg donor provides the eggs produced after the ovulation cycles which can be used to fertilize with the male gamete and produce embryo in invitro condition and then transferred to the mother's womb where the development is required to be done. A surrogate mother provides her womb for the implantation of the embryo developed outside her body to allow intra-uterine development of the embryo. The surrogate mother can be an animal mammal like female goat, sheep, or even a human female.
