metaphase I of meosis
independent assortment
The law of independent assortment is most directly related to the metaphase I stage of meiosis. During metaphase I, homologous chromosomes line up randomly at the equatorial plate, independently of each other, before separating into different daughter cells. This random alignment contributes to the independent assortment of alleles from different genes located on non-homologous chromosomes.

Law of independent assortment
The separation of homologous chromosomes during anaphase I of meiosis is responsible for Mendel's Law of Segregation. This process ensures that each gamete receives only one copy of each chromosome pair, leading to the independent assortment of alleles.
The exception to Mendel's law of independent assortment is when genes are located close together on the same chromosome and therefore tend to be inherited together, rather than independently assorting during meiosis. This is known as genetic linkage.
(Mendel's law of) independent assortment. This states that the chromosomes can line up along the equatorial line in 2^23 different arrangements (in humans- but 2^n in other animals with a different number of chromosomes)
The law of independent assortment. This principle states that genes located on different chromosomes segregate independently of each other during the formation of gametes, leading to a random combination of alleles in the offspring.
Independent assortment does not happen in mitosis, it happens in meiosis. In metaphase I of meiosis, synapsed homologous chromosomes align independently of one another along the metaphase plate. That is to say, one aligning in a certain fashion has no effect on another aligning in a certain fashion. In mitosis, chromosomes are exact copies of the parental cell's and independent assortment is a method of achieving genetic variation, which does not happen in mitosis.
Linked genes are an exception to Mendel's law of independent assortment, where genes located on the same chromosome tend to be inherited together. This is because they are physically close to each other and are less likely to undergo independent assortment during meiosis.
Gene linkage us considered an exception to Mendel's Law of Independent Assortment.
The law states that alleles at different loci separate independently of one another.
