For example, let us consider a pea plant, where homozygous tall plant has two alleles such as TT on their gene loci in their homologous chromosomes and homologous dwarf plants is represented by the allele tt. (researchtweet.com)
During the process of gametogenesis, the two homologous alleles TT and tt are separated and each chromosome contains a single allele as T and t and it is passed via gametes. (researchtweet.com)

This tool is based on the assumption of equal segregation of alleles during gametogenesis, allowing scientists to anticipate the potential outcomes of mating between organisms with known genotypes. (microbiologynote.com)
Mendel's Law of Segregation states that alleles for a trait separate during gamete formation, ensuring each gamete carries only one allele, randomly inherited from the parent. (microbiologynote.com)
By ensuring that each gamete receives only one allele from each gene pair, segregation allows for different combinations of alleles to be passed down to the next generation. (microbiologynote.com)
This principle, proposed by Gregor Mendel , states that individuals possess two alleles for a specific characteristic, and during the formation of gametes, these alleles segregate or separate from each other. (microbiologynote.com)
In simpler terms, if an individual carries two different alleles for a particular trait (heterozygous), such as one allele for brown eyes and another for blue eyes, these alleles separate during the formation of gametes. (microbiologynote.com)
