Are these chromosomes replicated or non-replicated?

What is the genotypic ratio for the generation that results from a cross between two heterozygous individuals?

A cell is placed into a hypertonic solution. Which direction will water move?

If a germ-line cell from an owl contains 8 picograms of DNA during G1 of interphase, how many picograms of DNA would be present in each cell during prophase I of meiosis?

The most common form of gene therapy involves inserting a normal gene into cells that contain a defective version of the gene.  In order to use gene therapy to prevent a man from passing a defective gene on to future generations, you should try to insert normal copies of the gene into
