Vedclass · Answer

(B) Mendel's Law of Segregation states that the two alleles of a gene pair segregate from each other during the formation of gametes.In a monohybrid cross,when $F_1$ hybrids (heterozygous,$Aa$) are self-pollinated,the $F_2$ generation produces offspring with genotypes $AA$,$Aa$,and $aa$ in a ratio of $1:2:1$.However,the phenotypic expression of $AA$ and $Aa$ is the same (dominant trait).Therefore,the phenotypic ratio observed in the $F_2$ generation is $3:1$ (three dominant to one recessive).

According to Mendel's Law of Segregation,the phenotypic ratio of the $F_2$ generation will be.................
