Detailed explanation-1: -Law of segregation is the second law of inheritance. This law explains that the pair of alleles segregate from each other during meiosis cell division (gamete formation) so that only one allele will be present in each gamete.

Detailed explanation-2: -1: The Law of Segregation states that alleles segregate randomly into gametes: When gametes are formed, each allele of one parent segregates randomly into the gametes, such that half of the parent’s gametes carry each allele.

Detailed explanation-3: -The law of segregation states that the parental genes must separate randomly and equally into gametes during meiosis so there is an equal chance of the offspring inheriting either allele.

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. Mendel was studying genetics by performing mating crosses in pea plants.

Detailed explanation-5: -These ‘laws’ are now known to be due to key events that occur during meiotic division: The law of segregation describes how homologous chromosomes (and hence allele pairs) are separated in meiosis I. The law of independent assortment describes how homologous pairs align randomly (as bivalents) during metaphase I.
