All The Best!!
,Question 1 (Multiple Choice)
According To The Biological Species Concept, Two Individuals Are Members Of The
Same Species If...(Pick The Best End To This Sentence)...
A) They Can Interbreed In The Laboratory
B) Their Dna Sequences Are > 95% Similar
C) They Can Potentially Interbreed Under Natural Conditions
D) They Regularly Interbreed In Nature
The Biological Species Concept Defines Species Based On The Potential To Interbreed
Under Natural Conditions And Produce Viable, Fertile Offspring.
Question 2 (Multiple Choice)
As You Climb Up A Mountainside, You Notice A Dramatic Decrease In The Size Of The
Flowers Produced By The Lovely Mountain Plant Rhinanthus Minor. Being A Person Of
Great Curiosity With Rigorous Scientific Training, You Perform A Transplant
Experiment Where Seeds Collected From Wild Plants At Both High And Low Elevations
Are Planted In Common Gardens At Both High And Low Elevations. Which Of The
Following Results Suggests That The Phenotypic Variation In Flower Size With
Elevation You Originally Observed Among Wild Populations Has Both A Genetic Basis
And Is Influenced By The Environment?
A) Average Flower Size Is Larger At The High Elevation Garden Than The Low
Elevation Garden, And Within Each Garden All Flowers Are Pretty Much The Same Size
,B) Plants Grown From High Elevation Seed Produce Smaller Flowers Than Those
Grown From Low Elevation Seed, And Average Flower Size Does Not Differ Between
High And Low Elevation Gardens
C) Average Flower Size Is Larger At The Low Elevation Than The High Elevation
Garden, And Within Each Garden Plants Grown From High Elevation Seed Produce
Larger Flowers Than Those Grown From Low Elevation Seed
D) Average Flower Size Is Smaller At The High Elevation Garden Than The Low
Elevation Garden, And Within Each Garden Plants Grown From High Elevation Seed
Produce Smaller Flowers Than Those Grown From Low Elevation Seed
This Shows Environmental Influence (Different Gardens) And Genetic Influence (Seed
Origin Differences).
Question 3 (Multiple Choice)
Extrapolating What We Know About The History Of Live On Earth To Other Potentially
Life-Supporting Planet In Our Galaxy, Who Would You Send On A Mission To Discover
Extra-Terrestrial Life?
A) A Virologist
B) A Zoologist
C) A Bacteriologist
D) A Botanist
Early Life On Earth Was Microbial, So Microbial Life Is Most Likely Elsewhere.
Question 4 (Multiple Choice)
, You've Been Studying Natural Selection On Body Size In The Fall Peeper, A Small Frog
That Hatches In The Spring From Eggs Laid The Previous Fall, Grows All Summer,
Reproduces And Lays Eggs In Late October, And Then Dies. In Summer 2020, You
Measured Body Size Of A Very Large Sample Of Male Peepers And You Return In The
Fall To Measure The Body Size Of Males That You Observe In The Act Of Mating With
Females. Which Of These Results Suggest Would Stabilizing Selection On Body Size?
A) Both The Mean And The Variability In Body Size Is Similar Between Summer And
Fall Samples
B) The Mean Body Size Is Higher In The Summer Than In The Fall But There Is No
Difference In Variability Between Samples
C) No Difference In Mean Body Size But The Variability Of Body Size Is Lower In Fall
Than Summer
D) Both The Mean And The Variability In Body Size Is Higher In The Summer Sample
Than In The Fall Sample
Stabilizing Selection Reduces Variation While Keeping The Mean Constant.
Question 5 (Multiple Choice)
If You Set Up 100 Experimental Populations Of Fruit Flies Each With A 75% Frequency
Of The "A" Allele And A 25% Frequency Of The "A" Allele And Keep The Populations
At A Size Of 30 Flies And Also Ensure That Gene Flow And Natural Selection Does Not
Occur In These Populations, Then Which Of The Following Results Would You Not
Expect?
(I) More Populations Lose The "A" Allele Than The "A" Allele
(II) More Populations Lose The "A" Allele Than The "A" Allele
(III) Allele Frequencies In Each Population Will Fluctuate Randomly Until One Or Other
Allele Is Lost
(Iv) Within Populations The Frequency Of The "A" Allele Will Steadily Increase
