Typically, biologically male individuals have one X and one Y chromosome (XY) while those who are biologically female have two X chromosomes. In this article we are trying to explain the facts that supports the question Do plants have chromosomes and the number of chromosomes found in different plant species. The plant is native to mainland China and Taiwan and is also grown commercially in New Zealand and California. Strawberries can also be octoploid with eight sets or decaploid for ten sets. Number of chromosomes or any abnormalities related with them is determined by the process called Karyotyping. http://www.newton.dep.anl.gov/askasci/m e00596.htm, http://www.mpsaz.org/pakupfer/49docs/08 -straw.pdf. Chromosomes are thread like coiled structures that are present inside the nucleus in both plants and animal cells. 3, 2 (2016). They are called sex chromosomes: The mother gives an X chromosome to the child. Sugarcane (Saccharum officinarum) is an allopolyploid that contains high chromosome number of 2n=100 to 130 in different types of strains.

As pointed out by Edger et al.15, the genome is an allopolyploid, arising from multiple rounds of gametic nonreductions and cross pollination events. This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope. The complete sequence of the octoploid strawberry provides insight into the elements that shape functional subgenome interactions. Generally, Potato (Solanum tuberosum) varieties are tetraploid (2n= 4x=48) with 12 chromosomes. Experiment to purify DNA from fruit Bananas, kiwis and strawberries all work well. The work by Edger et al.8 shows that the subgenome derived from the diploid F. vesca dominates in gene number and gene expression. Trends Plant Sci. A .
