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.
Answer: There is a 50% chance that the offspring will inherit Huntington's disease
Explanation:
Huntington's disease is expressed by a dominant allele.
Since the father is heterozygous for Huntington's disease, his genotype would be as follows:Hh
Even though he carries a normal allele, the dominant allele is disease causing and thus masks the effects of the normal allele, therefore he expresses the disease.
The mother does not have Huntington's because she is homozygous recessive, in other words, she carries 2 copies of the normal alleles.with the genotype hh.
If you do a punnet square, and you cross the mother and father, the following genotypes can be produced:
Hh, Hh, hh, hh
Therefore, there's a 50% chance that the offspring will inherit the disease causing allele and 50% chance that the offspring will not inherit it.

Answer:
Answers. Using the given measurements of both figures, set up a proportion that has the corresponding parts in the same position. Then solve the proportion using cross products to find the value for the unknown. Then, cross multiply to solve for x, and that sound give the missing measure.Answers.
