LSU BIO 1001 EXAM NEWEST 2024
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
