- Increasing uncontrolled poaching acts as some kind of <em>"selective pressure"</em>.
- Animals that carry the genes to grow tusks are removed from the population, and most of the surviving animals are those that do not have tusk and that carry the gene for tusklessness.
- Tuskless animals get to reproduce more frequently, transmitting the tusklessness gene to their progeny, and hence, increasing its frequency in the population.

Due to technical problems, you will find the complete question, the answer, and the explanation in the attached files.
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.
