Practice question # 1 What is the
probability that they will have a
colorblind child?
75 %
25 %
50%

25% probability,

as shownthe method the teacher in the video has used is using the punnet square,

and this question is a mono-hybrid cross type question, hence it is easier,

every mono-hybrid cross by the punnet square will give the following ratio,

=> dominant(homogeneous) : dominant(heterogeneous) : recessive

in this case,

=> normal (homogeneous pair) : normal (heterogeneous pair) : color-blind (homogeneous pair)

=> 1:2:1

which would be out of four possibilities, there is only one possibility of the child born to be color-blind

the answer should be d) he was one of those young thousands who greeted the war with a certain amount of relief, welcoming the liberation from webs of tangled emotion" since it is the best option because it shows his desire to free himself. 

hope this answer you! have a great day.
