It consists of two stages of
growth and one stage of
division
What is
the Cell Cycle?
(Cell Cycle stages are
Interpahse, Mitosis and
Cytokinesis)
The phase in Interphase
during which the cell
prepares for division and the
centrioles replicate
What is
Growth 2 or Gap 2 (G2)?
Interphase has three stages:
G1 – Rapid growth and
metabolism
S – DNA synthesis and
replication
G2 – Preparation for division
and centriole replication
During this stage, (1) spindle
fibres break down and
disappear, (2) a nuclear
membrane form around each
of the two new sets of
chromosomes and (3) the
cytoplasm divides between
the two halves of the cell
What is Cytokinesis?
It consists of two sister
chromatids held together by a
centromere
What is
Chromosome?
They are identical genetic
copies of each other
What are
Sister Chromatids?
Increase the number of
cells, regenerate damage
tissues, and replace dead
cells
What is
the function of mitosis?
Third phase of mitosis where
the centromeres splits apart
and the chromatids are pulled
to the opposite poles of the
cell by the spindle fibre
What is Anaphase?
The product of mitosis
What is
two genetically identical
Daughter Cells?
Caused by toxic substances,
radiation or viruses, these
changes become permanent
error and become copied
during Prophase
What are Mutations?
In plant cells, this must
develop between the two
newly forming cells in order
for cell walls to properly
separate
What is a Cell Plate?
The production of
reproductive cells called
gametes
What is
the function of Meiosis?
Similar chromosomes that
form pairs during Prophase I
What are
Homologous chromosomes?
It occurs in Prophase I when
non-sister chromatids wind
around each other and
exchange segments of
chromosomes to create new
genetic combinations in the
gametes
What is
Crossing Over?
Eight
What is
the number of phases in
Meiosis?
It is term defining the end
result of meiosis (i.e., the
production of gametes that
are either egg or sperm)
What is Gametogenesis?
When this allele is present, it
is the trait that will always be
expressed (i.e., appears)
What is Dominant?
The offspring produced by
cross of the two different
purebred parents of the P
Generation
What is
Filial Generation
or
F1 Generation
or
Hybrid?
It is the law that states that
inherited traits are
determined by pairs of
“factors” AND the factors
separate so that there is one
factor in each gamete
What is
the Law of Segregation?
The Mendelian Ratio in the F2
Generation that occurs in a
monohybrid cross
What is 3:1?
(Dominant Trait is expressed
75% of the time and the
Recessive Trait occurs 25%
of the time)
Term for an
organism with one
dominant allele and
one recessive allele
What is
Heterozygous Dominant?
PpRr
What is
a heterozygous dominant
gentoype?
It is the ratio of F2 Generation
offspring produced by
crossing two hybrid F1
Generation organisms
(i.e., heterozygous dominant)
What is 9:3:3:1?
It is the only way the
recessive traits can be
expressed in the F2
Generation of a dihybrid
cross
What is
if all alleles in the genotype
are recessive (e.g., pprr)?
It is the law that states that
the inheritance of alleles
for one trait do not affect
the inheritance of alleles
for another trait
What is
the Law of
Independent Assortment?
Genetic cross between
hybrids that
differ in two traits
What is
a Dihybrid Cross?
