BIOL 1104 Unit 4 Test Questions with
Correct Answers
2 types of traits - CORRECT ANSWER -Discrete and continuous
Continuous traits - CORRECT ANSWER -
Follow a distribution and often produced by many gene regions working together
Discrete traits - CORRECT ANSWER -
Can be readily classified into one of a series of types, colors or shapes; may or may not be gen
erated by one or many gene regions
Polymorphism - CORRECT ANSWER -Multiple descrete traits in a population
Heritable traits are shaped by? - CORRECT ANSWER -
Genes being expressed and translated proteins
Diploid gene - CORRECT ANSWER -One copy from each parent
Haploid gene - CORRECT ANSWER -Only one copy
ex: mitochondrial genes
Alleles - CORRECT ANSWER -Gene copies
Homozygous - CORRECT ANSWER -2 identical alleles
Heterozygous - CORRECT ANSWER -2 distinct alleles
, Evolution - CORRECT ANSWER -The diversity of traits changes over a long period of time
Evolution (change) - CORRECT ANSWER -
Not the same as the proposed mechanisms that allow for evolution
Microevolution - CORRECT ANSWER -The change in trait or frequency over time
Macroevolution - CORRECT ANSWER -
Change becomes associated with some form of isolation or discontinuity and we can distinguis
h the populations readily.
Speciation - CORRECT ANSWER -
The separation of ancestral populations into a distinct species; Macroevolution
Ex: Darwin's finches
Fitness - CORRECT ANSWER -Result of survival and reproduction
Alleles and genotypes can be monitored - CORRECT ANSWER -
Electrophoresis of proteins or nucleic acids with different size or change.
Various methods of DNA sequencing
Electrophoresis - CORRECT ANSWER -Separation in an electric field
Alleles may be classified by - CORRECT ANSWER -
Where they migrate under electrophoresis or the specific DNA bases identified in a portion of
DNA
