Part A - Independent assortment of three genes A wild-type tomato plant (Plant 1) is homozygous dominant for three traits: solid
Effectus [21]
<h2>Law of independent assortment </h2>

Explanation:

  • There are 8 distinct phenotypes, each one has a 12,5% of appearance: Since M=solid leaves D=normal height P= smooth skin.
  • Recessive gene characters can only be taken in homozygous recessive mmddpp.  

      1. MmDdPp: M=solid leaves D=normal height P= smooth skin.

     2. MmDdpp M=solid leaves D=normal height pp= peach skin.

    3. MmddPp M=solid leaves dd=dwarf height P= smooth skin.  

    4. Mmddpp M=solid leaves dd=dwarf height pp= peach skin.

    5. mmDdPp mm=mottled leaves D=normal height P= smooth skin.  

    6. mmDdpp mm=mottled leaves D=normal height pp= peach skin.  

    7. mmddPp mm=mottled leaves dd=dwarf height P= smooth skin.  

   8. mmddpp mm=mottled leaves dd=dwarf height pp= peach skin.

Hence,The answer is all eight possible phenotypes from the cross MmDdPp x mmddpp are equally likely, resulting in a phenotypic ratio of 1:1:1:1:1:1:1:1
