Problem
 All
of
the
following
make
meiosis
different
from
mitosis,
EXCEPT:
 a. 
meiosis
comprises
two
divisions.
 b. 
chromosome
number
is
reduced
by
half
in
meiosis.
 c. 
resul.ng
cells
from
meiosis
are
gene.cally
different
 from
the
parent
cell.
 d. 
meiosis
lacks
preceding
S
and
G2
phases.
 e. 
pairing
of
homologous
chromosomes
usually
only
 occurs
in
meiosis.
 Prac.ce
Problem
 Most
body
(nonreproducEve)
cells
of
humans
and
other
 mulEcellular
eukaryotes
have
two
sets
of
each
chromosome.

 Such
cells
are
______
and
the
matching
pair
of
chromosomes
 are
called
_________.
 a. 
diploid;
homologous
chromosomes
 b. 
haploid;
homologous
chromosomes
 c. 
diploid;
sister
chroma.ds
 d. 
tetraploid;
sister
chroma.ds

Problem
 According
to
Mendel’s
Second
Law,
when
the
different
 alleles
for
one
trait
separate
into
gametes,
their
 separaEon:
 a.  is
dependent
upon
how
different
alleles
for
 other
traits
separate.
 b.  is
independent
of
how
different
alleles
for
other
 traits
separate.
 c.  occurs
so
as
to
prevent
recessive
alleles
of
two
 different
genes
from
occupying
the
same
 gamete.

 d.  occurs
so
that
recessive
alleles
of
different
genes
 always
occupy
the
same
gamete.
