Part A - Independent assortment of three genes A wild-type tomato plant (Plant 1) is homozygous dominant for three traits: solid leaves (MM), normal height (DD), and smooth skin (PP). Another tomato plant (Plant 2) is homozygous recessive for the same three traits: mottled leaves (mm), dwarf height (dd), and peach skin (pp).

Law of independent assortment

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

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
