Here is a strawberry karyotype -
ignore the different colours.

strawberry?
How many alleles could an individual
strawberry have at each locus?
Finally during the G2 stage of cell
division, how many double helixes
would be in this picture if you drew
them over the chromosomes?
Many domesticated plants are
polyploid - give one possible reason
