Answer: percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Explanation: First, homozygous means each parent have matching chromosomes (Like XX, instead of Xx)
Lets make a punnet square and show the data. We will use 'S' for spotted and 's' for solid
The punnet square shows that the percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Hope this helps :)
Answer: 20 ± 11.32
Explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values where there is a % certainty the true mean value lies in. For example, a 95% CI means there is a 95% certainty the true mean value lies in the interval.
For the data set 2, z-value for 95% confidence interval is z = 1.96
Formula to calculate CI is
x ±
where
x is mean
z is z-value
s is standard deviation
n is the sample number
Then:
20 ±
20 ±
20 ±
20 ± 11.32
The 95% CI is 20 ± 11.32, which means there is a 95% certainty the true value is between 8.68 and 31.32.
