Even when equilibrium is reached, particles of a solution will continue to move across the membrane in both directions. However, because almost equal numbers of particles move in each direction, there is no further change in concentration. Hope i did it right _-_
Answer:
27/64 or 0.421
Explanation:
When AaBbCC X AaBbCc :
A_B_C_ = 27
aaB_C_ = 9
A_bbC_ = 9
A_B_cc = 9
aabbC_ = 3
A_bbcc = 3
aaB_cc = 3
aabbcc = 1
Out of the total 64 offspring, 27 will have at least one dominant allele for each of the three genes hence these 27 offspring will show dominant trait for all genes. So the probability of producing a dominant trait for all genes will be 27/64 or 0.421
