Practice question 1 What is the probability that they will have a colorblind child 75 25 50 class=

Respuesta :

Answer:

50%

Explanation:

Every human has 46 chromosomes. 23 from mom, and 23 from dad. As you may now, chromosomes carry you genes, and your genes are parts of your DNA. So there would be a 50% chance the the child will be colorblind.  

Answer:

25% probability,

as shown....the 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
