Answer:
B. 25%
Explanation:
Assuming the trait for teeth size is represented by the allele A. large teeth size is dominant and will be represented by A while small teeth size will be represented by a.
Assuming that the population of 1,000 [piranhas are all heterozygotes and they crossbreed with one another:
Aa x Aa = AA, Aa, Aa and aa
The ration of piranhas with large teeth to that of the small teeth is 3:1 or 75:25.
Hence, about 25% of the next generation of the population is ecpected to have small teeth.
The correct option is B.

Answer:Genetic engineering, also called recombination DNA technology, involves the group of techniques used to cut up and join together genetic material, especially DNA from different biological species, and to introduce the resulting hybrid DNA into an organism in order to form new combinations of heritable genetic material.
Explanation:
Answer:
Human insulin protein will not be produced
Explanation:
For production of human insulin protein in bacteria, first the insulin gene needs to be transcribed to corresponding mRNA. This mRNA will be then translated to produce insulin protein. The initial portion of any gene has a promoter sequence. During transcription RNA Polymerase recognizes this promoter sequence to initiate the process.
Here, the gene's first five nucleotides were accidentally cut out so now the promoter sequence has been altered. RNA Polymerase will not be able to recognise it so transcription will not occur. No mRNA will be formed and as a result translation will also not occur and there will be no production of insulin protein.
