Answer:
1/2

You have a 1/2 chance of having a boy and a 1/2 chance of having a girl. 
Unless the question specifies whether or not there is a mutation present with the male parent, it is safe to assume there is a 50/50 shot of having a boy or girl.

Answer:
The correct answer is -
A. a, c, g
B. e, b, f & d
Explanation:
Part A- the options a, c, g are the options that show mutation or replacement by a single base change
a) Phenylalanine: UUU UUC
 Leucine: UUA UUG
Only one base change
c) Alanine:  GCU  GCC  GCC GCG
    Thr:         ACU ACC ACA ACG
only one base change
g) Prolin:  CCU CCC  CCA  CCG
   Serine: UCU UCC  UCA UCG
Part B:
All other replacements will not be consistent with the Genetic Code if single base substitutions occur in option e, b, f & d
