Hawaiian happy face spiders from the island of Maui can have different markings, as shown below. A single gene determines the markings on the spiders. A plain spider is crossed with a patterned spider. The patterned spider is h0m0zygous. The pattern allele is dominant to the plain allele.

What percentage of the offspring from this cross are expected to be patterned instead of plain?
