Explanation:

The use of persons genetic makeup or information or genome, to select or choose the medicine and dosage of the drugs to be administered  that will likely work t for that particular person is called Pharmacogenomics . This  field of science combines the knowledge of how drugs work, called pharmacology, with the knowledge of the human genome, called genomics.

The aim of Pharmacogenomics is to optimize drug therapy, with consideration on the patients' genotype. Moreover it targets to ensure maximum efficiency with minimum adverse reactions. By utilizing pharmacogenomics, we have a high hope that drug treatments can veer away from the "one-dose-fits-all" approach to medication.

In one type of plant, orange petals (O) are dominant over yellow petals (o) and tall stems (T) are dominant over short stems (t)
vodka [1.7K]

Answer No 1:

The set up of the punnet square is shown in the attached diagram. As the alleles assort independently hence the gametes formed will be OT,Ot,OT,Ot and OT,Ot,oT,ot. These will be the outcomes of the possible gametes formed. When these gametes are cross bred, the results are shown in the diagram attached.

Answer No 2:

The outcomes of each possible genotype are:

OOTT = 2/16

OOTt = 4/16

OOtt = 2/16

Oott = 2/16

OoTT = 2/16

OoTt = 4/16

Answer No 3:

The likelihood of each possible offspring phenotype is:

Orange petals with tall stem  and orange petals  with small stems present in ratio 12:4 i.e. 3:1.

20. Does facilitated diffusion require energy for the cell?
Vera_Pavlovna [14]

Answer: no

Explanation: The solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. This process is called passive transport or facilitated diffusion, and does not require energy.
