	}
Create a new Genotype which consists of the chromosomes from the given
{@code fromIndex} (inclusively) to the given {@code toIndex} (exclusively).
This method creates a <em>view</em> of the underlying chromosomes.

@since 7.2

@param fromIndex the start chromosome index, inclusively
@param toIndex the end chromosome index, exclusively
@return a new genotype consisting of the chromosomes within the given
        indexes
@throws IndexOutOfBoundsException for an illegal end point index value
         ({@code fromIndex < 0 || toIndex > length() || fromIndex > toIndex}).
