Biology 1407- Lecture Exam 1 Questions With Complete
Solutions
"2pq" Correct Answers frequency that are heterozygous
"p" Correct Answers frequency of "B" allele
"p+q=" Correct Answers 1
"p2" Correct Answers frequency that are homozygous
dominant
"q" Correct Answers frequency of "b" allele
"q=" Correct Answers 1-p
"q2" Correct Answers frequency that are homozygous
recessive
absolute dating Correct Answers any method of measuring the
age of an event or object in years
adaptive radiation Correct Answers An evolutionary pattern in
which many species evolve from a single ancestral species
age of the earth Correct Answers 4.6 billion years
Allele Correct Answers Different forms of a gene
,allele frequency Correct Answers Number of times that an
allele occurs in a gene pool compared with the number of alleles
in that pool for the same gene
allopatric speciation Correct Answers something physically
separates a population. Over time, different mutations arise in a
subpopulation
allopolyploidy Correct Answers combining chromosomes from
2 different species
apomorphies Correct Answers specialized or derived character
state
archaean Correct Answers the earlier of the two formal
divisions of Precambrian time, the period when life first formed
on Earth. Name means beginning
artificial selection Correct Answers Breeding organisms with
specific traits in order to produce offspring with identical traits.
assortative mating Correct Answers the type of mating that
occurs when an organism selects a mating partner that resembles
itself
autapomorphies Correct Answers a unique derived character
Autopolyploidy Correct Answers chromosome duplication in a
single species
, behavioral Correct Answers individuals reject or fails to
recognize potential mating patterns
biases associated with the fossil record Correct Answers
existed for a long time
were abundant and widespread
were marine
had hard parts
binomial system of nomenclature Correct Answers gives
species a unique name "scientific name"
biological Correct Answers species are groups of actually or
potentially interbreeding populations that are reproductively
isolated from other such groups.
bottle neck Correct Answers process in which a large
population declines in number, then rebounds
branching tree: Correct Answers as the lineages continue to
split it forms a history tree
characteristics of the first life forms Correct Answers small,
single celled, no nucleus. Little internal structure, no external
appendages, in group called prokaryotes
clade Correct Answers a group of taxa that includes all of its
common ancestors
Colonization Correct Answers One country taking over another
area to be used for their benefit
