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
metabolismS – DNA synthesis and
replicationG2 – 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 areSister 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 areHomologous 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 betweenhybrids that
differ in two traits
What is a Dihybrid Cross?
