Answer:
Genetic engineering has its grass roots from the recombinant technology.
Explanation:
Genetic engineering is seen to have started from a scientists activity which involved restriction enzymes and DNA ligases that were used by Paul Berg in 1972 to create the first recombinant DNA molecules. A monkey virus which is SV40 was combined with a lambda one. Following that, the results of the experiment and attempts were further investigated by other scientists and later, the first plant that underwent genetic engineering was the plant tobacco.
Yes, those that use external fertilization are more likely to produce large numbers of sperm and eggs.

Answer:
- According to the cladogram what separates rabbits/primates from crocodiles is that the former have a divergence before the latter and are viviparous.
- The organism that is most closely related to rodents and rabbits in the cladogram is the primate.
Explanation:
The cladogram (see image) shows the evolutionary line that several animal species have followed. According to this, the following conclusions can be established:
- <em>Both primates and rabbits/rodents are mammals, with intrauterine development of their offspring, while crocodiles and birds are oviparous, which represents a </em><em><u>divergence in their evolution</u></em><em>.</em>
- <em>The species most related in the cladogram to rabbits / rodents is the primate, since they share several characteristics in common, such as being mammals, skin covered with hair and being viviparous.</em>
Characteristics such as these are what allow the classification of different animal species.
