segregationMendel's first law; The separation of the members of a homologous pair of
chromosomes into different
gametes through the process of
meiosisSource: Jenkins, John B. 1990.

Full article >>>(2) Genetically, the production of two separate
phenotypes, corresponding to two
alleles of a
gene, either in different individuals ( meiotic
segregation) or in different
tissues (mitotic
segregation).
Full article >>>The
segregation of differentiating
traits is
Mendel's First Law.
The 3:1 ratio is consistent with each
plant having two copies of the "
gene" and randomly passing one copy through the
gametes (pollen or
egg).
Full article >>>Mendel's law of
segregation essentially has three parts.
Alternative versions of genes account for
variations in inherited
characters. This is the concept of
alleles.
Alleles are different versions of genes that impart the same
characteristic.

chromosomes to opposite sides of the
cell. Distribution of
alleles on
chromosomes into
gametes during
meiosis.
Full article >>>Segregation The normal biological process whereby the two pieces of a
chromosome pair are separated during
meiosis and randomly distributed to the germ
cells.

Full article >>>segregation the separation of
homologous chromosomes during
anaphase 1 of
meiosis, producing
gametes containing only one
allele of each
gene.
Full article >>>Law of
SegregationThe principles that govern
heredity were discovered by a monk named Gregor
Mendel in the 1860's. One of these principles is now called
Mendel's law of
segregation.
Full article >>>law of
segregationMendel's first law, stating that
allele pairs separate during
gamete formation, and then randomly re-form pairs during the fusion of
gametes at
fertilization.

Full article >>>Principle of
SegregationMendel's principle of
segregation states that paired factors (genes) separate during
gamete formation (
meiosis).
Full article >>>Post-meiotic segregation The type of
segregation produced when a
recombinant DNA molecule contains an uncorrected mismatched
base pair; at the next
replication, normal
base pairing occurs producing one mutant
progeny and one
wild-type progeny.
Full article >>>principle of
segregation One of
Mendel's observations on the behavior of
hereditary units during
gamete formation.
Full article >>>Related Terms:
SegregationThe separation of allelic differences from one another.
Segregation may occur at the first or second
division of
meiosis, or at the first
mitosis after
meiosis (postmeiotic
segregation).
Full article >>>: The situation referring to
segregation of two or more genes together as a unit.
Genetic linkage is thought to arise to accommodate genes that function best in each other's company, i.e.

proteins.
DNA replication involves thousands

Full article >>>This statement is often called
Mendel's rule of
segregation.
If an
organism has two unlike factors (we call them
alleles) for a
characteristic, one may be
expressed to the total exclusion of the other (
dominant vs
recessive).

localized to the early endocytic pathway and have been shown to share a number of
characteristics to merit their
segregation into a single functional endocytic group.
