Question:
Polyploidy level of cultivated strawberry
Polyploidy level of cultivated strawberry
Show Hint
Remember that while the wild woodland strawberry (Fragaria vesca) is diploid ($2n = 2x = 14$), the cultivated garden strawberry is octoploid ($2n = 8x = 56$).

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Ploidy refers to the number of homologous sets of chromosomes in a biological cell.
The genus Fragaria features a natural ploidy series ranging from diploid to decaploid species.
Step 2: Detailed Explanation:
The commercial garden strawberry, botanically known as Fragaria $\times$ ananassa, is an octoploid species ($2n = 8x = 56$).
It is an artificial hybrid that originated in Europe during the 1750s.
The parental species of this hybrid are two wild octoploid species: Fragaria virginiana (native to eastern North America) and Fragaria chiloensis (native to the coast of South and North America).
This high ploidy level contributes to larger fruit size and higher vigor compared to most diploid wild strawberries.
Step 3: Final Answer:
The cultivated strawberry has an octoploid ($8x$) genome.
