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
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
Caused by toxic substances, radiation or viruses, these
changes become permanent error and become copied
during Prophase
In plant cells, this must develop between the two
newly forming cells in order for cell walls to properly
separate
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
It is term defining the end result of meiosis (i.e., the
production of gametes that are either egg or sperm)
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 3:1?
(Dominant Trait is expressed 75% of the time and the
Recessive Trait occurs 25% of the time)
It is the ratio of F2 Generation offspring produced by crossing two hybrid F1 Generation organisms
(i.e., heterozygous dominant)
It is the law that states that the inheritance of alleles for one trait do not affect the inheritance of alleles
for another trait
