m_a_m_a [10]

Answer:

12 : 3 : 1

Explanation:

According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and  1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.

<em>Dihybrid cross for heterozygous summer squash:</em>

                    WG         Wg            wG            wg          

    WG      WWGG   WWGg     WwGG     WwGg

    Wg       WWGg   WWgg     WwGg      Wwgg

    wG        WwGG    WwGg     wwGG      wwGg

      wg       WwGg    Wwgg     wwGg        wwgg

   Genotypes:

   W-G-  and W- gg  = white = 12

    ww G- = yellow = 3

     ww gg = green = 1
