Document Summary

If you measure the length of an object once, it is safe to assume that this value may be . Select one: accurate, precise, both accurate and precise, neither accurate nor precise. The correct answer is: d. neither accurate nor precise. If you measured the length of an object 3 times using the same ruler and got the same value each time, then you could be certain this would be indicative of. If you measured the length of an object 5 times using the same ruler which you checked against a standard length. Each measurement of the object gave the same value you could be certain this would be indicative of. Select one: great accuracy, great precision, both great accuracy and precision, neither great accuracy nor precision. The correct answer is: c. both great accuracy and precision. A measurement cannot be precise unless it is also accurate.

1) Enter a numerical decimal fraction.Last week you were wondering what Jessica and Tom's babies might look like with respect to their eyebrows and earlobes (both Tom and Jessica have thick eyebrows, controlled by gene E, with thick eyebrows dominant to thin eyebrows, and both of them have free earlobes, controlled by gene F, with free earlobes dominant to attached earlobes). You know that Tom's mom has attached earlobes. Additionally, Tom's mom has thin eyebrows, and so does Jessica's dad. No one in Jessica's pedigree going back to her great grandparents are known to have had attached earlobes, so you assume that she must be homozygous for this trait. If your inferences based on their known pedigrees are correct, what is the probability that Jessica's and Tom's first baby will have free earlobes and thin eyebrows?

Years pass, and Jessica and Tom just had a kid, and they send you a picture of the three of them. You are surprised to see that the baby has thin eyebrows and attached earlobes.

What does this tell you?

Select all the answers that apply:

Select one or more:

a. At least some of Jessica's direct ancestors must be carriers for the recessive allele of gene E, including at least one of her parents.

b. Jessica's dad must be 'true-breeding' for both gene E and gene F.

c. Jessica's mom must be a carrier for gene E.

d. Jessica's genotype must be Ee Ff.

e. Given what you know now about Jessica and Tom's genotypes after seeing their first baby, you realize that prior to inception, the chances of their child showing the thin eyebrow, attached earlobe phenotype was only 1/16.

f. Tom's genotype must be Ee ff.
