Answer:
D. DDT
Explanation:
DDT is highly persistent in the environment means that it break down very slowly in the environment. The half-life for DDT is from 2 to 15 years. Half-life is the time needed for the degradation of half of the compound. Persistent bio-accumulative toxic substances (PBTs) are chemicals that break down slowly in the environment and its accumulation in living organisms are toxic. Some PBTs are dispersed through air currents while some uses other environmental pathways, resulting in contamination of regions far from their points of origin.

Answer:
III3 will be "pp" lower case p
II2 will be Pp
Explanation:
As we know the trait is caused by dominant alleles. III3 is not affected so she will have two recessice alleles so 2 lower case p.
III2 is affected so the person will have one dominant allele P and one recessive. The dominant is from the father and the recessive is from the mother.
Hope that helps
