Let's say that the genotype of the couples are:
Cc and Cc. Notice that one is capital and the other is not. This is what shows that they are heterozygous. We put this now in a Punnet Square:
C c
C CC Cc
c Cc cc
This means that there is a 75% chance that their children will have a cleft-chin and 25% will not.
The probability is the same with each off-spring. So the answer would be 75% chance the same probability for all subsequent children.
Plants need to carry out both photosynthesis to get food which the formula is CO2 + 2H2A + photons ==> [CH2O] + 2A + H2O <span>and cellular respiration keeps the plant alive maning its empature and vitals.
hope this helps.
