proteins. It is comprised of mostly Intron Sequences
A. Noncoding DNA
B. coding DNA
C. Structural

What are the steps in order of the development process? - answer
Cell Division (division of zygote)
Differentiation (expression to specialization)
Pattern Formation (Blueprint)
Morphogenesis (growth, division, migration, shape, apoptosis)
What is the relationship between cell determination and cell
differentiation?
A. determination follows differentiation
B. differentiation follows determination
C. differentiation occurs in prokaryotes and evolved into
determination in eukaryotes
D. Determination makes a cell into a specific kind, and then
differentiation makes the cell into something completely different. -
answer B. Differentiation follows determination
(Determination is based on positioning)
What is determination? - answer All possible cell fates based on
position in embryo, interactions , and time it takes to develop.
What is differentiation? - answer Gene expression determine fate
of cell
,What is the correct order of the cell potency from least to most
limited?
A. Multipotent, Pluripotent, Unipotent, Totipotent
B. Totipotent, Multipotent, Pluripotent, Unipotent
C. Multipotent, Totipotent, Pluripotent, Unipotent
D. Totipotent, Pluripotent, Multipotent, Unipotent - answer D.
Totipotent, Pluripotent, Multipotent, Unipotent
What is evolution? - answer Change of allele frequency over time,
and populations of organisms over time.
What is the bottleneck effect? - answer when a small number of
individuals are contributing gametes to the next generation, the
alleles they carry may not represent all the alleles found in the
parent population.
Which of the following must be true for evolution by natural
selection?
A. Variability
B. Heritability
C. Selection
D. A and B only
E. All of the above - answer E. All of the above
What are the 5 Mechanisms of Evolution? - answer Mutation, Gene
Flow, Genetic Drift, Selection, Nonrandom Mating.
What is variation? - answer Individuals within a population are
variable.
, What is heritability? - answer Variations among individuals are
passed from parent to offspring.
Which of the following in NOT an assumption made for the
determination of the Hardy-Weinberg Value?
A. natural selection does not occur
B. mating is random
C. the population is finite and defined
D. there is no immigration and no emigration
E. mutations do not occur - answer C. the population is finite and
defined
What is the Hardy-Weinberg Principle? - answer Hardy and
Weinberg determined that the proportions of genotypes in a
population will remain constant assuming:
No mutation takes place, no genes are transferred to or from other
sources, mating is random, the population is very large, no selection
occurs.
When is a population is Hardy-Weinberg Equilibrium? - answer
When the proportion of genotypes does not change, the population
is said to be in HBE
What are the different types of numerous reproductive isolating
mechanisms? - answer Pre-zygotic: ecological isolation, behavioral,
temporal, mechanical, prevention of gamete fusion
Post-zygotic: hybrid inviability or infertility (sterile, itself cannot
reproduce)
Differences in courtship rituals and mating calls describe what kind
of reproductive isolation?
A. Ecological
