Detailed explanation-1: -The law of segregation is the second law of heredity. This law explains that the pair of alleles separates from each other during the cell division of meiosis (formation of gametes), so there is only one allele in each gamete. In a single-hybrid cross, both alleles are expressed in the F2 generation without mixing.

Detailed explanation-2: -Genes come in different versions, or alleles. A dominant allele hides a recessive allele and determines the organism’s appearance. When an organism makes gametes, each gamete receives just one gene copy, which is selected randomly. This is known as the law of segregation.

Detailed explanation-3: -Mendel’s law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene.

Detailed explanation-4: -During meiosis, alleles segregate, or separate, such that each gamete is equally likely to receive either one of the two alleles present in the diploid individual. Mendel called this phenomenon the law of segregation, which can be demonstrated in a monohybrid cross.

Detailed explanation-5: -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.
