Therefore, communication between cells is crucial for plant survival.
Answer:
%
Explanation:
Given
Cystic fibrosis is caused by the allele f, which is completely recessive to the normal dominant allele F. Thus if "F" and "f" occur together then the characteristics associated with allele "F" will be expressed.
Or a person having cystic fibrosis must have genotype "ff"
A punnet square cross between the parents having genotype "Ff" is as given below-
F f
F FF Ff
f Ff ff
Thus, out of four offspring only one is having the "ff" genotype. Thus the
chance that their second child will have cystic fibrosis is
