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?
