Answer:
Step-by-step explanation:
a. The possible outcome
From the given information, the parents have the genotype red/blond and the pair of allele determines the hair color.
Let R represents red
Let B represent blond
Check attachment for crossing.
So, we have four outcomes which are red/red, red/blond, blond/red, blond/blond.
correct option is A
red divided by red comma red divided by blond comma blond divided by red comma and blond divided by blond
b. Probability of having the same blond is given as
Here, there are 4 outcomes red/red, red/blond, blond/red, blond/blond
Therefore,
The blond/blond occurs once out of the the four possible outcomes, then the probability of the parent having blond blond is
P(blond/blond)=1/4
P(blond/blond)= ¼
c. Probability of red hair colour is
P(red/anything)
Here, there are 4 outcomes red/red, red/blond, blond/red, blond/blond
P(red/anything)=3/4=0.75
red occurs three time and it is only once that red did not occur out of 4 total outcome.
P(red/anything) =3/4
