BIO 340 HOLECHEK EXAM TWO QUESTIONS WITH
DETAILED VERIFIED ANSWERS; ALREADY GRADED A
_______ ________ measures the number of independent
measurements in your data - correct answer- Degrees of
Freedom
_______ gene encodes phenylalanine hydroxylase, an enzyme
that
converts the amino acid phenylalanine into tyrosine - correct
answer- PAH
................AA/ Aa /aa
Pop. 1: 0.81 /0.18 /0.01
Pop 2: 0.25 /0.50 /0.25
Calculate the Fixation index in the Subpopulation relative to the
Total population based on the information provided. - correct
answer- 0.19
"consequence of variance" is known as the - correct answer-
Wahlund effect
,"p" is equal to the ratio of what set of alleles? - correct answer-
dominant
(Allelic series of the C gene):
- c^ch produces a "dilute" phenotype called ______. - correct
answer- chinchilla
(Allelic series of the C gene):
- c^h produces a phenotype called _______ with
little pigment on the body but full color on the
extremities - correct answer- Himalayan
(Allelic series of the C gene):
- wild type allele, C, produced a functional enzyme and ____
____ ____. - correct answer- full coat color
(Allelic series of the C gene):
,c is a fully recessive null allele and produces an
______ phenotype - correct answer- albino
(observed-expected)^2 /
Expected
This equation is added to all other columns of data in question
and is summed to deliver what value? - correct answer- Chi
Squared
***Exam Question*** Wild type blue-eyed Mary has blue
flowers. Two genes control the pathway that makes the blue
pigment: The product of gene W turns a white precursor into
magenta pigment. The product of gene M turns the magenta
pigment into blue pigment. Each gene has a recessive loss-of-
function allele: w and m, respectively. A dihybrid (WwMm) is
self-pollinated. What proportion of the offspring will be
magenta? - correct answer- 3/16
1-(obs/exp) is the formula for what?Keep in mind you could use
percentages as whole numbers or as decimals but you need
both the observed and expected to be displayed in the same
manner for this to work. - correct answer- Interference

individuals:

The table shows the distribution of the number of bristles in a
Drosophila population indicating how many individuals in the
population have those particular number of bristles. Calculate
the variance for the number of bristles in the entire population.
12:3:1 ratio - correct answer- dominant epistasis
13:3 ratio - correct answer- dominant suppression
