WebJul 28, 2024 · The segregation law is Mendel’s first law. It states that during meiosis alleles segregate. The fundamental principles of this law are posited as follows: There can be more than one type of allele for a gene. During the process of meiosis, when gametes are formed, the allele pairs segregate, i.e. they separate.

WebDec 7, 2024 · The Law of Independent Assortment states that during a dihybrid cross (crossing of two pairs of traits), an assortment of each pair of traits is independent of the other. In other words, during gamete formation, one pair of trait segregates from another pair of traits independently. This gives each pair of characters a chance of expression.
