Detailed explanation-1: -It states that during meiosis alleles segregate. The fundamental principles of this law are posited as follows: There can be more than one type of allele for a gene. During the process of meiosis, when gametes are formed, the allele pairs segregate, i.e. they separate.

Detailed explanation-2: -The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells. The segregation of gene variants, called alleles, and their corresponding traits was first observed by Gregor Mendel in 1865. Mendel was studying genetics by performing mating crosses in pea plants.

Detailed explanation-3: -During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random. This means that all of the maternal chromosomes will not be separated into one cell, while the all paternal chromosomes are separated into another.

Detailed explanation-4: -Second, the Law of Segregation states that the two alleles for each gene separate from each other during gametogenesis so that the parent may only pass off one allele; thus, the offspring can only inherit one allele from each parent.

Detailed explanation-5: -In Meiosis I homologous chromosomes segregate, while in Meiosis II sister chromatids segregate. Most multicellular organisms use meiosis to produce gametes, the cells that fuse to make offspring.
