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

romanna [79]
Yes, it is possible that evolution occurs in this case.

At first, the new insecticide is effective against the boll weevil. Spraying the insecticide will kill the boll weevil in a way. The insecticide might attack boll weevil enzyme or any part of its organs.<span>
But some of them might have a mutation that renders the insecticide ineffective. The mutation probably happens to DNA that code the enzyme or protein that targeted by the insecticide, makes the insecticide completely ineffective.
The next spray will kill all old organism, leaving the new resistant organism in less competition area. This will allow the resistant organism to grow fast and eventually replace all the old organism in the area.</span>
