Fill in the Blanks Biology 9: Mendel's LawsOnline version Biology 9: Mendel's Laws by Tharwat A 1 expressed F1 contrasting one dominance both 3 F2 Law of explains that in a monohybrid cross between a pair of traits , only parental character will be in the generation and parental characters will be expressed in the generation in the ratio : 1 . 2 without one present F2 segregation blending four monohybrid one meiosis Law of is the second law of inheritance . This law explains that the pair of alleles segregate from each other during cell division ( gamete formation ) so that only allele will be in each gamete . In a cross , both the alleles are expressed in the generation any . Thus , the law of segregation is based on the fact that each gamete contains only allele . This law is based on basic concepts . 3 assortment alleles independent influence not color sorted independently shape another Mendel's law of states that the of two ( or more ) different genes get into gametes of one another . In other words , the allele a gamete receives for one gene does the allele received for gene . Example : Pea and pea gene s
