Gregor Mendel
Mendel's theory, known as the laws of inheritance, includes the concepts of segregation and independent assortment. The law of segregation states that alleles for a trait separate during gamete formation, ensuring that offspring inherit one allele from each parent. The law of independent assortment posits that the distribution of one pair of alleles into gametes does not affect the distribution of another pair, leading to genetic variation. These principles laid the groundwork for modern genetics by explaining how traits are passed from parents to offspring.
This theory is known as Mendelian genetics. It involves the principles of segregation, stating that alleles of a gene separate during gamete formation, and independent assortment, which states that alleles of different genes assort independently of each other during gamete formation. These principles were established by Gregor Mendel in the 19th century through his experiments with pea plants.
During Mendel's time, inheritance was not well understood. Many believed in the blending theory, which suggested that offspring inherited a blend of traits from their parents. Mendel's work on pea plants challenged this notion and laid the foundation for the modern understanding of inheritance through the principles of segregation and independent assortment.
The theory is known as Mendelian genetics, proposed by Gregor Mendel. It states that traits are determined by discrete units of inheritance (genes) located on chromosomes, which segregate during gamete formation and assort independently during inheritance.
The theory of independent assortment, proposed by Gregor Mendel, states that the alleles for different genes segregate independently of one another during the formation of gametes. This means that the inheritance of one trait does not influence the inheritance of another trait, leading to a variety of possible genetic combinations in offspring. This principle applies to genes located on different chromosomes or those far apart on the same chromosome. However, genes that are close together on the same chromosome may be inherited together, a phenomenon known as genetic linkage.

The Gene Theory is one of the basic principles of biology. The main concept of this theory is that traits are passed from parents to offspring through gene transmission. Genes are located on chromosomes and consist of DNA. They are passed from parent to offspring through reproduction. The principles that govern heredity were introduced by a monk named Gregor Mendel in the 1860's. These principles are now called Mendel's Law of Segregation and Law of Independent Assortment.
The theory of independent assortment, proposed by Gregor Mendel, states that the alleles for different genes segregate independently of one another during the formation of gametes. This means that the inheritance of one trait does not influence the inheritance of another trait, leading to a variety of possible genetic combinations in offspring. This principle applies to genes located on different chromosomes or those far apart on the same chromosome. However, genes that are close together on the same chromosome may be inherited together, a phenomenon known as genetic linkage.
Mendel's conclusions, based on his pea plant experiments, included the principles of segregation and independent assortment. These principles describe how genes are passed down from parent to offspring. The chromosomal theory of inheritance later connected Mendel's principles to the physical basis of heredity by identifying chromosomes as the carriers of genetic information, thus explaining how genes are inherited and expressed through the process of meiosis and fertilization.

The principle is known as Mendel's Law of Independent Assortment. This law states that during meiosis, different genes segregate independently of each other, leading to random distribution of chromosomes to gametes.
In the early 1900s, the rediscovery of Gregor Mendel's work on inheritance was bolstered by the identification of chromosomes as carriers of genetic information. Scientists like Walter Sutton and Theodor Boveri proposed the chromosomal theory of inheritance, which linked Mendel's principles of heredity to the behavior of chromosomes during cell division. This provided a molecular basis for Mendel's laws of segregation and independent assortment, validating his ideas about how traits are passed from one generation to the next.
Mendel's conclusion on the segregation and independent assortment of traits laid the groundwork for Darwin's theory of natural selection by providing a mechanism for how variation is passed down from one generation to the next. This understanding of how traits are inherited allowed Darwin to propose that natural selection acts on this variation to drive the evolution of populations.
