Answer:
1/2
Step-by-step explanation:
Since the recessive gene is carried in the x chromosome and a father can only pass it to a daughter, the father doesn't have the disease nor carries it.
The mother carries the recessive gene because her father passed her his conditioned gene (only having one x chromosome), while her mother gave her a normal one so she can have normal vision.
The chance of having a boy or a girl is 1/2 and the chance of this baby of having both recessive gene is null because in order to have a girl that is color blind both her x chromosomes must have the recessive gene, but the father can't pass it since he doesn't carries it. Therefore the combined probability is 1/2*(1-0) = 1/2.
Answer:
2In4x= 2In8 ln(16x^2) = ln64 Multiply e by both sides.
Step-by-step explanation:
If 1 of 25 is 101.6 ( 2540/25)
Then 23 is 2336.8 (23*101.6)
The Mississippi river is 2336.8 miles long
