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
