BIOL 1104 Unit 4 Test Questions with
Correct Answers 2025-2026
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
