ACTUAL EXAM TEST BANK COMPLETE
QUESTIONS AND CORRECT DETAILED
ANSWERS (VERIFIED ANSWERS)
Where are the 3 major check points - Answer-Juncture of G1 to S
Juncture of G2 to mitosis
between metaphase and anaphase
Results of mitosis - Answer-2 diploid cells produced, each identical to parents (clones)
Results of meiosis - Answer-four haploid cells, differ from parent and one another
Reproduction by mitosis produces genetically identical offspring - Answer-Asexual
Reproduction by meiosis shuffles the genes to produce genetically unique offspring -
Answer-Sexual
Meiosis consists of one round of DNA replication, followed by two rounds of nuclear
division. t/f - Answer-True
In meiosis I, homologous sister chromatids pair and then separate from each other. t/f -
Answer-True
In meiosis II, two sister chromatids of each unduplicated chromosome are separated
from each other. t/f - Answer-False; duplicated chromosomes
Fusion of two haploid nuclei produces haploid (n) nucleus in the zygote. t/f - Answer-
False; A diploid
Homologous pairs do not interact with each other (mitosis/meiosis) - Answer-Mitosis
Homologous pairs become zippered together and crossing over occurs
(mitosis/meiosis) - Answer-Meiosis
Homologous chromosomes separate from each other (mitosis/meiosis) - Answer-
Meiosis
sister chromatids of a chromosome separate from each other (mitosis/meiosis) -
Answer-Both
, The genetic variability that occurs from one generation to the next results almost entirely
from meiosis and sexual reproduction in 3 areas - Answer-1. random alignment of
chromosomes during metaphase I
2. crossing over during prophase I
3. Random combination of gametes at fertilization
Location of mitosis - Answer-Somatic cells
Location of meiosis - Answer-Germ cells
A random combining of maternal and paternal homologues (alleles) - Answer-
Independent assortment
Male and Female gametes unite and nuclei fuse together, the fusion of 2 haploid nuclei
produces diploid nucleus in the zygote - Answer-Fertilization
Asymmetric division - Answer-Oogenesis
Symmetric division - Answer-Spermatogenesis
separates the pairs of homologues, with each daughter nucleus receiving one - Answer-
Meiosis I
Separates the chromatids and parcels one chromatid into each of two more daughter
nuclei - Answer-Meiosis II
The result from incorrect separation of chromosomes in meiosis, causes gametes to
have too many/ too few chromosomes (meiosis I and II) - Answer-Nondisjunction
The ultimate source of variation; gives rise to new alleles - Answer-Mutations
Asexual/ in sponges, anemones and hydra - Answer-Budding
Asexual/ splitting to form 2 smaller individuals that then regenerate missing parts.
Corals, annelids, sea stars, flatworms - Answer-Fission
Asexual/ growth and development of embryos occur without fertilization. bees, insects,
fish, amphibians, reptiles. "females born pregnant" - Answer-Parthenogenesis
Sexual/ produce eggs and sperm - Answer-Separate sexes
Sexual/ sperm and eggs are produced in the same individual (relatively immobile from
other members) - Answer-Hermaphrodites
Sexual/ both parents release sperm/eggs into water "spawning" requires synchronized
reproductive behavior - Answer-External fertilization
