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

Answer:
A thylakoid is a sheet-like membrane-bound structure that is the site of the light-dependent photosynthesis reactions in chloroplasts and cyanobacteria. It is the site that contains the chlorophyll used to absorb light and use it for biochemical reactions.
