The expansion of gases takes place because of kinetic energy provided by heat which excites the molecules and causes them to move further apart. On cooling the atoms in a gas lose their energy and slow down coming closer together.
Answer:
Let's consider the alleles for a true- breeding inflated pod to be PP. Let's consider the alleles for the constricted pod to be pp. The punnet square for this can be shown as:
p p
P Pp Pp
P Pp Pp
The results from the punnet square show that there will be 100% (4:0) inflated pods offsprings produced from this cross. However, their genotype will be heterozygous.
A cross between the constricted pods can be shown as:
p p
p pp pp
p pp pp
The results from this cross show that the offsprings produced will be 100% constricted pod plants.
Fertilization often takes place in the Uterus
