(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).

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).

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.

Law of Segregation
The 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.

law of segregation

Principle of Segregation
Mendel's principle of segregation states that paired factors (genes) separate during gamete formation (meiosis).

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.

Related Terms: Segregation
The 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).

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).

Rabs 5, 21 and 22 have all been 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.
