Answer:
The correct answer is (b)-False
Explanation:
Bacteria do not undergo meiosis or mitosis to reproduce and increase its genetic recombination. To increase their genetic recombination bacteria take the help of horizontal gene transfer through which it gets the genetic material of another bacteria. This new gene helps bacteria to survive in the challenging environment.
Bacteria divide through binary fission in which one cell of bacteria divides into two equal daughter cell each having its genetic material because genetic material of parent cell segregate equally into both the cell.
Therefore bacteria do not undergo meiosis or mitosis.
Variations in evolution usually refers to variation of genes at a particular loci. This differs from diversity which is the total of genetic differences within a population. Speciation is the reproductive isolation of a subset of a population.

Explanation:
<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
