pentaploid การใช้

• This results in increased ploidy levels that range from triploid to pentaploid in wild-caught individuals.
• There is one pentaploid cultivated species ( with 60 chromosomes ) : " S . curtilobum ".
• This was hypothesized to be a pentaploid formed from spores of " A . pinnatifidum " and apogamous triploid spores of " A . ?trudellii ", but this was not cytologically verified.
• All strawberries have a base haploid count of 7 chromosomes . " Fragaria ?bringhurstii " is pentaploid, having 5 pairs of these chromosomes for a total of 35 chromosomes, 7 from the " F . vesca " parent, and 28 from the " F . chiloensis " parent.
• Wild potatoes, of which there are about 200, are predominantly diploid ( 2 ?12 = 24 chromosomes ), but triploid ( 3 ?12 = 36 chromosomes ), tetraploid ( 4 ?12 = 48 chromosomes ), pentaploid ( 5 ?12 = 60 ) and even hexaploid ( 6 ?12 = 72 chromosome ) species or populations exist.
