|
|
Separate genes are passed independently from each other, from parent to offspring.
|
|
|
Every individual possesses two alleles for any particular trait and which allele a parent gives its offspring is completely random.
|
|
|
Just because an allele is dominant, doesn’t mean it is inherited more often.
|
|
|
A recessive allele is expressed less than a dominant allele.

Detailed explanation-1: -The law of segregation states that each individual that is a diploid has a pair of alleles (copy) for a particular trait. Each parent passes an allele at random to their offspring resulting in a diploid organism. The allele that contains the dominant trait determines the phenotype of the offspring.
Detailed explanation-2: -According to the law of segregation, only one of the two gene copies present in an organism is distributed to each gamete (egg or sperm cell) that it makes, and the allocation of the gene copies is random.
Detailed explanation-3: -Law of segregation: During gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene. Law of independent assortment: Genes for different traits can segregate independently during the formation of gametes.
Detailed explanation-4: -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.
Detailed explanation-5: -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.
