Genetics Problem Solving Chapter 25

See the answer below

Explanation:

1.      Tt   x   Tt

   TT  Tt   Tt   tt

Assuming that T is dominant over t:

Genotype ratio = 1TT:2Tt:1tt

Phenotype ratio = 3:1

2.     Rr   x   Rr

    RR   Rr   Rr   rr

Assuming that R is dominant over r:

Genotype ratio = 1RR:2Rr:1rr

Phenotype ratio = 3:1

3.  Assuming that green (G) is dominant over the other color (g). Heterozygous green would be Gg

        Gg   x   Gg

     GG   Gg   Gg   gg

Genotype ratio = 1GG:2Gg:1gg

Phenotype ratio = 3:1 (green ratio the other color)

4. Assuming that green (G) is dominant over the other color (g) as above:

  homzygous green plant = GG; heterozygous green plant - Gg

      GG   x   Gg

   GG   Gg   GG   Gg

Genotype ratio = 1GG:1Gg

Phenotype ratio = 100% green

5. Assuming that tall (T) is dominant over short (t)

Homzygous tall plant = TT

short plant = tt

         TT   x   tt

       Tt   Tt   Tt   Tt

Genotype ratio = 100% Tt

Phenotype ratio = 100% tall

archaebacteria are found in in forest soil.

hope i spelled it right lol

hope i
