Answer:
1/2 or 50%
Explanation:
This question involves a single gene coding for the number of digits per paw in cats or humans. The allele for polydactyly i.e six digits (P) is dominant over the allele for normal number of digits i.e 5 (p).
According to this question, If a man who is heterozygous (Pp) for this trait marries a woman with 5 fingers (pp), the following gametes will be produced by each parent:
Pp : P and p
pp : p and p
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Pp, Pp, pp and pp
The offsprings with genotype Pp will have polydactyl, hence, the chances that they will have a child with polydactyly is 1/2 or 50%.
Answer:
Option C
Explanation:

Solution
It is given that the membrane is permeable to both salt and water.
Thus, water will form region of high concentration to the region having low salt concentration. The same applies to the movement of water molecule.
As we can see in the image, Side A has higher water concentration and side B has higher salt concentration.
Thus water will move from side A to side B and Salt will move from side B to side A.
Hence, option C is correct
Answer:
Fracture of the lower jaw following tooth extraction is a rare and severe complication, occurring most often in the preangular region following third molar extraction. When left untreated, pseudoarthrosis can occur.
