Mendel's Law of Segregation
The law of Segregation explains how traits are passed from one generation to the next.
Mendel crossed tall and short homozygous plants to study inheritance. All F1 offspring were tall.
When F1 plants self-pollinated, the F2 generation produced both tall and short plants.
Mendel reasoned that the two genes inherited from each parent separated during gamete formation, ensuring that only one gene is passed to each gamete.
This process became evident during reproduction when F1 plants produced two types of gametes—50% carrying the uppercase T allele and 50% carrying the lowercase t allele.
When these gametes combine, there is a 25% chance of homozygous dominant TT, a 50% chance of heterozygous Tt, and a 25% chance of homozygous recessive tt. Since a plant with at least one copy of the dominant allele becomes tall, the ratio is 3:1 in the F2 generation.
From these results, Mendel’s Law of Segregation was formulated. It states that the two copies of each gene separate during gamete formation, ensuring that each gamete carries only one allele for a given trait.
